Lessons · 7 blocks

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Shop Hazard Recognition and OSHA 10-Hour General Industry	24	theory	Students identify and classify the principal hazards in a CNC machining shop—machine-point-of-operation, caught-in/between, struck-by, electrical, chemical, and noise—and correctly apply the OSHA General Industry hierarchy of controls to each.	Complete all ten modules of the OSHA 10-Hour General Industry course (OSHA-authorized provider content), including quizzes, and submit the completion card application. Conduct a guided walkthrough of the school shop using a provided hazard-identification checklist; students photograph at least eight distinct hazards, classify each by type, and propose a control measure using the hierarchy of controls. Review three real OSHA inspection citations from metalworking facilities (redacted), identify the violated standard for each, and write a one-paragraph corrective-action memo in plain English.	OSHA 10-Hour General Industry course materials (authorized provider), OSHA 29 CFR Part 1910 reference (online), shop hazard-checklist form, PPE kit (safety glasses, hearing protection, steel-toed boots, cut-resistant gloves), camera or smartphone for documentation.	OSHA 10 course completion certificate issued by the authorized provider; additionally, a scored 25-question hazard-recognition quiz—students must score 80% or higher to advance.
2	Lockout/Tagout, PPE Selection, and Emergency Response	20	demo	Students correctly execute a full six-step lockout/tagout procedure on a de-energized training machine, select task-appropriate PPE for three different machining operations, and demonstrate first-aid and CPR/AED skills to the standard required for a recognized certification card.	Instructor demonstrates LOTO on the shop's vertical mill using the school's written LOTO program; students then individually perform a supervised LOTO procedure on the same machine and on a bench grinder, with an instructor checklist recorded for each attempt. PPE selection exercise: students receive three job cards describing different operations (face milling aluminum, thread-tapping stainless, solvent degreasing) and must assemble the correct PPE kit for each, citing the relevant OSHA standard or SDS requirement. Complete a recognized first-aid and CPR/AED course (minimum one full day, hands-on with manikins and a trainer AED unit); practice scenario: a coworker receives a chip-laceration and another collapses—students manage both simultaneously in a timed drill.	School LOTO program document, OSHA 29 CFR 1910.147 reference, individual padlocks and lockout hasps, lockout tags, multi-lock hasp, training-mode AED unit, CPR manikins, first-aid kit, PPE samples (various glove ratings, face shields, respirators), job-card scenario sheets.	LOTO practical checklist: all six steps performed in correct sequence with zero omissions on two separate machines—any missed step is an automatic fail and requires a full repeat; CPR/AED card issued by the certifying organization; PPE selection exercise graded pass/fail (all three scenarios correct = pass).
3	Trade Math: Whole Numbers, Fractions, Decimals, and Unit Conversion	22	theory	Students solve machining-context arithmetic problems—stock sizing, feed-and-speed ratios, decimal-to-fraction conversion, and inch-to-metric conversion—with an accuracy rate of 85% or higher on a timed, no-calculator quiz.	Work through a structured problem set of 40 machining-context problems (e.g., 'A shaft is 2-7/16 inches in diameter; convert to decimal inches and then to millimeters') using pencil-and-paper drill before any calculator is allowed, building mental estimation habits first. Paired activity: each student writes five stock-sizing word problems from a set of blueprint excerpts and exchanges with a partner to solve; instructor reviews and corrects errors in a whole-class debrief. Timed 30-question quiz (45 minutes, no calculator) covering all four operation types in machining context; errors are categorized by type on a returned error-analysis sheet so students know exactly which skill to revisit.	Tabor and Peterson 'Math for the Machinist' or equivalent trade-math textbook, blueprint excerpt packet, scientific calculator (for checking only), graph paper, pencils, error-analysis tracking sheet.	30-question timed quiz scored by instructor; 85% (26/30) required to pass; students below threshold receive targeted remediation problems and one retest within the same course week.
4	Trade Math: Geometry, Trigonometry, and Tolerance Arithmetic	22	theory	Students apply right-triangle trigonometry, the Pythagorean theorem, and bilateral/unilateral tolerance arithmetic to solve bolt-circle, taper, and fit-class problems typical of NIMS Level 1 exam questions.	Instructor-led worked examples on a whiteboard: bolt-circle coordinate calculation, sine-bar taper setup angle, and calculating the maximum material condition of a shaft with a bilateral tolerance; students copy and solve parallel problems simultaneously. Lab sheet: students use a scientific calculator to solve 20 graded problems drawn directly from NIMS Machining Level 1 study guides (measurement and calculation domain), recording each step to show method, not just answer. Group error-hunt: instructor provides six 'completed' tolerance calculations that each contain one deliberate error; teams identify and correct the error, then explain in one sentence why the error would cause a defective part.	Scientific calculator, NIMS Machining Level 1 study guide (NIMS publication), whiteboard and markers, printed bolt-circle and taper problem sheets, tolerance error-hunt handout.	20-problem lab sheet graded for both method and answer; 85% accuracy required; NIMS study-guide problems are tagged so students see their performance against the actual credential domain before the formal exam.
5	Measurement Instruments and Technical Drawing Fundamentals	24	lab	Students correctly use a steel rule, 0–1-inch outside micrometer, 6-inch vernier caliper, and combination square to measure provided specimens and record readings within ±0.001-inch of the instructor reference value.	Instrument clinic: instructor demonstrates zeroing, care, and reading technique for each of the four instruments; students immediately measure the same four specimen blocks independently and compare readings to an instructor-measured reference sheet, identifying and correcting any reading error before moving on. Measurement scavenger hunt: students receive a set of ten mixed specimens (hex stock, rod, flat bar, a threaded bolt) and a blank data table; they must select the most appropriate instrument for each feature, measure it, and justify their instrument choice in writing. Introduction to basic orthographic drawing: students receive three simple single-view and two two-view drawings of shop parts and must correctly identify: projection angle (third-angle), hidden lines, centerlines, and dimension lines—completing a labeled markup sheet for each drawing.	0–1-inch outside micrometers (class set), 6-inch vernier calipers (class set), 12-inch steel rules, combination squares, measurement specimen block set (calibrated), orthographic drawing packet, ASME Y14.5 one-page reference card, measurement data table forms.	All ten specimen measurements recorded; each reading must be within ±0.001 inch of the instructor reference value—more than two out-of-tolerance readings requires a full instrument-use review and retest; orthographic markup sheets graded, minimum 80% of features correctly identified.
6	Technical Reading, SDS Interpretation, and Digital Shop Tools	18	practice	Students extract all setup-relevant information from a machining work order, locate and interpret a chemical SDS for a cutting fluid, and use at least two digital tools (shop ERP job-tracking and a cloud-based file-sharing system) to submit a completed job packet.	Work-order decode exercise: students receive a realistic multi-step CNC mill work order (matching the format used by a local employer partner) and complete a structured extraction form covering material, tolerances, required tools, finish specification, quantity, and delivery date—instructor reviews in class discussion. SDS deep dive: each student receives the SDS for a different common shop chemical (coolant concentrate, penetrating oil, aluminum cleaner) and must complete a one-page summary identifying the hazard class, required PPE, first-aid measures, and proper disposal method—then present findings to a small group for peer questions. Digital-tools walkthrough: instructor demonstrates the school's shop management or job-tracking software and the file-sharing/LMS platform; students log in, upload their completed work-order form and SDS summary as a single combined PDF, and confirm the instructor has received and can open the file.	Sample machining work orders (employer-provided or instructor-created realistic facsimiles), SDS packet (one per student, different chemicals), PPE reference chart, school shop management or ERP software (student logins), school LMS or cloud file-sharing platform, computers or tablets.	Work-order extraction form scored for completeness and accuracy (10 required data fields, at least 9 correct = pass); SDS summary graded pass/fail against a rubric (all four sections—hazard, PPE, first aid, disposal—must be correctly populated); digital upload confirmed by instructor.
7	Career Readiness, Professional Communication, and Credentialing Roadmap	18	field	Students produce a trade-specific resume and a completed job application, deliver a two-minute professional self-introduction, and construct a written credentialing roadmap that sequences NIMS Level 1, NIMS Level 2, Mastercam Associate, and Haas Certification milestones across the program.	Resume and application workshop: using a machining-industry resume template reviewed by a local employer advisory board member, students draft a resume targeting an entry-level CNC operator position; a classmate peer-reviews against a provided employer checklist (clear objective, measurable skills, no typos, correct contact info), and then a final version is submitted digitally. Professional self-introduction drill: students prepare and deliver a two-minute verbal introduction (name, trade goal, top skill, one professional question for the listener) in front of a small group; the group rates delivery using a provided rubric (clarity, eye contact, conciseness, professionalism); each student receives written peer feedback and records one personal improvement goal. Credentialing roadmap: using the NIMS, Mastercam, and Haas Automation credential-information pages, students build a one-page timeline showing when in the nine-to-twelve-month program they plan to sit each exam, what study resources they will use, and what employer or job outcome each credential supports—submitted as a living document they will update each semester.	Employer-reviewed resume template, blank job-application form (generic, realistic), peer-review checklist, self-introduction rubric, NIMS credential information (nims-skills.org), Mastercam Associate credential information (CNC Software, LLC website), Haas Certification information (haas automation HTE website), computers or tablets for document production.	Resume scored against employer-advisory rubric (minimum 80%—must have correct contact info, trade-specific skills section, and zero spelling errors); self-introduction rated by instructor minimum 3/4 on all rubric dimensions; credentialing roadmap graded complete/incomplete (all three credential families addressed = complete).

1	Engineering Drawing Fundamentals and the Title Block	12	theory	Students correctly identify and extract all mandatory information from the title block, revision block, and notes area of an ANSI/ASME Y14.1 engineering drawing.	Instructor-led walkthrough of a real machined-part drawing: students locate part number, revision level, material specification, finish, tolerances, drawing scale, projection angle, and approval signatures. Students complete a structured title-block extraction worksheet for three different drawings (a bracket, a shaft, and a housing) and compare answers in pairs. Class discussion of how revision changes affect already-machined parts; students mark up a sample drawing with a revision delta to show how the change propagates.	Assorted industrial engineering drawings (bracket, shaft, housing), ASME Y14.1 drawing standard summary handout, title-block extraction worksheet, pencils, highlighters	Worksheet scored: students must correctly identify 18 of 20 required fields across the three drawings (90%) to pass.
2	Orthographic Projection and Multi-View Drawing Interpretation	15	theory	Students correctly identify front, top, right-side, and auxiliary views in third-angle projection and reconstruct 3-D part geometry from a two- or three-view drawing.	Instructor demonstrates third-angle projection using a physical L-bracket model and a glass-box analogy; students sketch the six standard views from the model. Students work through a set of 10 multi-view exercises of increasing complexity, sketching the missing view for each incomplete drawing. Students use basic CAD viewer software (free Autodesk Viewer or equivalent) to rotate a 3-D model and validate their hand-sketched views.	Physical demonstration models (L-bracket, stepped shaft, angled block), graph paper, pencils, desktop or tablet with free CAD viewer, multi-view exercise packet	10-problem missing-view quiz: students must correctly draw 8 of 10 missing views (80%) with all visible and hidden lines in the correct positions.
3	Section Views, Auxiliary Views, and Detail Views	12	theory	Students interpret full sections, half sections, removed sections, broken-out sections, auxiliary views, and detail views on industrial drawings to extract hidden geometry used in CNC setup.	Instructor demonstrates the cutting-plane concept using a foam block cut in half; students sketch the resulting full-section view with correct hatch patterns per ASME Y14.2. Students interpret a complex housing drawing that includes a half section, an auxiliary view of an angled boss, and a detail view of a threaded hole, completing a feature-location checklist. Students create a simple section view sketch of a provided part drawing, correctly placing the cutting plane line, arrows, and hatch lines.	Foam demonstration block, ASME Y14.2 line-type reference card, industrial housing drawing (instructor-sourced), feature-location checklist worksheet, drafting pencils, graph paper	Feature-location checklist and section-view sketch evaluated: students must correctly identify all 12 features on the checklist and produce a section sketch with no missing hatch or incorrect line types (10 of 12 features minimum, 83%).
4	Dimensions, Tolerances, and Fits	14	theory	Students calculate maximum material condition (MMC), least material condition (LMC), and allowable variation for linear, angular, and diametral dimensions, and classify fits using ANSI/ASME B4.1 or B4.2 standards.	Instructor explains limit dimensioning, plus/minus tolerancing, and bilateral versus unilateral tolerances; students calculate MMC, LMC, and tolerance range for 15 dimension callouts. Students use an ANSI fit table to determine clearance, interference, or transition fit class for a shaft-and-bore pair given basic size and tolerance grade, then verify with a tolerance stack calculation. Students examine a set of sample turned shafts measured with a micrometer and determine which are in tolerance and which are out of tolerance for a given drawing callout.	ASME B4.1/B4.2 fit table handout, tolerance calculation worksheet, outside micrometer (0–1 in. and 1–2 in.), sample turned shafts (in- and out-of-tolerance set), calculator	Tolerance calculation quiz (20 problems): minimum 16 of 20 correct (80%); shaft accept/reject exercise: all 6 accept/reject decisions must be correct.
5	Surface Finish and Surface Texture Symbols	8	theory	Students correctly interpret ASME Y14.36 surface texture symbols on drawings, including Ra roughness values, lay direction, machining method callouts, and all-around indicators.	Instructor presents the ASME Y14.36 symbol anatomy using an annotated poster; students label each element of five different surface texture symbols from actual drawings. Students use a surface roughness comparator (machinist's reference tool with tactile and visual samples) to match a list of Ra values to corresponding machining processes (turning, milling, grinding, broaching). Students review a machined-part drawing and create a process note listing the required surface finish for each machined face, flagging any faces that require a secondary finishing operation.	ASME Y14.36 surface texture symbol reference card, surface roughness comparator set, annotated poster, part drawing with multiple surface finish callouts, process note worksheet	Symbol labeling exercise and process note: students must correctly interpret 9 of 10 surface texture symbols (90%) and correctly identify all faces requiring secondary finishing.
6	Introduction to GD&T: Philosophy, Rules, and Symbols	14	theory	Students explain the purpose of GD&T versus coordinate tolerancing, state Rule 1 and Rule 2 of ASME Y14.5, and correctly identify all standard GD&T characteristic symbols and their tolerance zone geometry.	Instructor demonstrates with physical gauges how a coordinate-toleranced hole location creates a square tolerance zone while a GD&T true-position callout creates a circular zone, showing how GD&T provides more usable tolerance. Students complete a symbol identification flashcard drill: given 30 cards each showing one GD&T symbol, students name the characteristic, its category (form, orientation, location, runout, profile), and describe the shape of the tolerance zone. Students apply Rule 1 to five drawing examples, determining whether perfect form at MMC is required or waived, and document their reasoning.	Physical gauge demonstration set (coordinate vs. position), ASME Y14.5-2018 standard (school copy or authorized excerpt), GD&T flashcard set (30 cards), Rule 1/Rule 2 worksheet, NIMS Blueprint Reading study guide	Symbol identification quiz: 27 of 30 symbols correctly named and categorized (90%); Rule 1 worksheet: 5 of 5 correct.
7	Datums, Datum Reference Frames, and Feature Control Frames	16	theory	Students identify primary, secondary, and tertiary datums on a drawing, construct the datum reference frame, and correctly read every element of a feature control frame in sequence.	Instructor demonstrates the 3-2-1 datum concept using a part resting on surface plate pins; students physically set up a rectangular block on a surface plate, identify which faces constrain which degrees of freedom, and label the datum reference frame. Students decode 12 feature control frames from industrial drawings, writing out a plain-English interpretation of each: what is being controlled, to what tolerance, at what material condition, and relative to which datums. Students sketch the datum reference frame for three different parts (prismatic, cylindrical, sheet metal) and identify the tool or fixture contact points that would establish each datum in a machining setup.	Surface plate, 1-2-3 blocks and pins, rectangular steel demonstration block, 12 feature control frame interpretation worksheet, industrial drawings (prismatic, cylindrical, sheet metal parts), pencils	Feature control frame interpretation worksheet: 10 of 12 frames correctly interpreted in plain English (83%); datum reference frame sketches reviewed by instructor with verbal explanation required.
8	Form and Orientation Tolerances	14	demo	Students interpret flatness, straightness, circularity, cylindricity, perpendicularity, angularity, and parallelism callouts and describe the physical tolerance zone each creates on a machined feature.	Instructor demonstrates flatness measurement on a granite surface plate using a dial test indicator: sweeps a milled plate and records the full indicator movement (FIM), then compares to the drawing callout. Students measure a set of four machined blocks with a dial indicator and height gauge to assess perpendicularity of a machined side wall to a datum face, record results on a measurement log, and make a conformance decision. Students interpret orientation and form callouts on a complex turned/milled part drawing and sketch each tolerance zone (zone shape, size, and orientation relative to datum) for six different callouts.	Granite surface plate, dial test indicator with magnetic base, height gauge, set of machined demonstration blocks (flat, perpendicular, angular features), complex turned/milled part drawing, measurement log form, ASME Y14.5-2018 reference	Measurement log: all four blocks correctly assessed for conformance (pass/fail decision matches instructor key); tolerance zone sketches: 5 of 6 correct (83%).
9	Location Tolerances: True Position, Concentricity, and Symmetry	16	demo	Students calculate true-position tolerance zones, apply MMC and RFS modifiers, and determine whether a measured hole or feature location conforms to a position callout using the formula and on a CMM or manual layout.	Instructor derives the true-position formula (diametral position error = 2 × √(Δx² + Δy²)) and works three examples; students solve six additional problems using coordinate measurements and the formula to determine pass/fail. Students measure a drilled plate with a digital caliper and height gauge using a datum reference setup on a surface plate, record actual hole center coordinates, calculate true position, and compare to the drawing callout at MMC. Instructor demonstrates use of a CMM (coordinate measuring machine) to verify hole positions on the same plate; students observe the CMM report and reconcile it with their hand-calculated results.	Drilled steel demonstration plate (multiple holes at known positions), digital calipers, height gauge, surface plate, angle plate, CMM (shop CMM or instructor demonstration), true-position calculation worksheet, scientific calculator	Calculation worksheet: 5 of 6 true-position problems solved correctly (83%); plate measurement: calculated position error within ±0.002 in. of instructor-measured reference value and correct conformance decision required.
10	Profile, Runout, and Free-State Tolerances	10	demo	Students interpret profile of a line, profile of a surface, circular runout, and total runout callouts and measure total runout on a turned part using a dial indicator and V-blocks.	Instructor explains profile tolerance zones (bilateral and unilateral) using a contoured template overlaid on a drawing; students interpret three profile callouts on a complex aerospace-style drawing and sketch the bilateral and unilateral zones. Students measure total runout on a stepped shaft using a dial test indicator and V-blocks, rotating the shaft 360° and recording FIM at three axial positions; they compare FIM to the drawing callout and record a conformance decision. Students calculate the difference between circular runout and total runout using two measurement scenarios and explain in writing why a part can pass circular runout but fail total runout.	Contoured profile template, complex drawing with profile callouts, stepped demonstration shaft, dial test indicator, V-blocks, surface plate, runout measurement log, ASME Y14.5-2018 reference	Runout measurement log: FIM recorded at all three positions and conformance decision correct; profile interpretation: 3 of 3 zone sketches correct; written runout explanation assessed by instructor for technical accuracy.
11	Reading a Complete Industrial Drawing: Lab Application	24	lab	Students extract all machining-relevant information from a complete, multi-sheet industrial drawing package and produce a fully annotated setup sheet suitable for CNC production.	Each student receives an assigned multi-sheet drawing package for a real or realistic machined component (e.g., a hydraulic manifold block or marine drive shaft flange) and independently completes a drawing interrogation checklist covering all dimensions, GD&T callouts, datums, surface finishes, material, and notes. Students produce a written setup sheet listing: raw material specification, all critical dimensions and tolerances grouped by setup (Op 10, Op 20, etc.), datum contact points, required tooling types (end mill, drill, bore, etc.), and inspection checkpoints with acceptance criteria. Students peer-review a classmate's setup sheet using a structured review checklist, flag discrepancies, and reconcile differences with the original drawing before submitting final versions to the instructor.	Multi-sheet industrial drawing package (assigned per student), drawing interrogation checklist, setup sheet template, peer-review checklist, pencils, highlighters, calculators, ASME Y14.5-2018 reference	Setup sheet graded against instructor answer key: must capture 100% of datums, 90% of critical dimensions and tolerances, and all surface finish and material callouts to pass; peer review participation is required.
12	Drawing Discrepancies, Non-Conformance, and Document Control	16	practice	Students identify conflicting, ambiguous, or incomplete drawing callouts and document a non-conformance report (NCR) following a standard shop process.	Students analyze a deliberately flawed drawing set (instructor-prepared with six seeded errors: conflicting tolerance, missing datum, undefined surface finish, incorrect projection view, obsolete revision, and an illegible note) and identify all errors in writing. Instructor explains document control basics: revision control, drawing release, engineering change orders (ECOs), and why only the current released revision may be used on the shop floor; students practice pulling the correct drawing revision from a simulated document control folder. Students complete a non-conformance report for a part that has been machined to an older drawing revision, documenting the discrepancy, affected dimensions, and recommended disposition (use-as-is, rework, scrap), following a standard NCR template.	Flawed drawing set (instructor-prepared, 6 seeded errors), simulated document control folder with multiple revisions, NCR template form, standard shop process reference sheet, pens	Error identification: must find at least 5 of 6 seeded drawing errors (83%); NCR form reviewed by instructor for completeness and correct disposition logic—must include all required fields to pass.

Students face both ends of the stock to establish length, then rough-turn the OD in 0.050 in DOC passes leaving 0.010 in of stock for finishing, recording spindle speed and feed used at each pass Students take a finish turning pass and measure the OD with a 1 in outside micrometer, calculating and applying a correction pass if outside tolerance before machining the shoulder to location Students grind or select a pre-ground HSS parting and grooving tool, plunge the undercut groove to specified width and depth, then measure groove width with a telescoping gauge and groove diameter with a micrometer	Engine lathe, 3-jaw chuck, HSS turning inserts or CCMT carbide inserts with appropriate toolholder, HSS parting/grooving tool, 1018 mild-steel rounds (1 in diameter × 6 in), 1 in outside micrometer, 0-1 in depth micrometer, dial caliper, surface-finish comparison chart (Ra 125 µin reference), engineering drawing for stepped shaft	All diameters within ±0.002 in, shoulder location within ±0.005 in, groove width within ±0.005 in, groove diameter within ±0.003 in, surface finish comparable to Ra 125 reference — instructor measures with calibrated micrometer; any single feature outside tolerance requires a re-run on a new blank
8	Taper Turning: Compound Rest and Tailstock Offset Methods	10.5	lab	Students produce a Morse taper shank using the compound rest method and verify fit with a blued taper-gauge test showing contact over at least 60% of the tapered surface.	Students calculate the compound rest angle from the taper callout on the drawing using the formula: angle = arctan(taper per foot ÷ 24), then set the compound rest to that angle and verify with a protractor Students rough and finish the taper in multiple compound-rest passes, maintaining consistent hand-crank feed rate to minimize chatter, and clean the surface with an abrasive cloth at a safe, non-rotating condition for minor burr removal Students blue the taper with Prussian blue layout dye, insert it into the matching socket (MT socket in a test block), rotate gently, withdraw, and inspect the contact pattern; they record the percentage contact and re-cut if below 60%	Engine lathe, 3-jaw chuck, carbide or HSS turning tools, Morse taper reference drawing (specify MT2 or MT3), compound rest protractor, Prussian blue layout dye, Morse taper test socket block, machinist's scale, surface-finish reference chart	Taper angle within ±0.5° of specified value verified by protractor and by the blue contact pattern showing at least 60% distributed contact; major diameter within ±0.005 in; instructor assesses both the bluing pattern and the dimensional check — fail on either requires re-work
9	Threading on the Lathe: External and Internal Single-Point Threads	17	lab	Students cut an external Unified National thread (at least 3/4-10 UNC) and an internal thread (tapped or single-point) that accept a mating part with smooth fit confirmed by hand thread-gauge or GO/NO-GO check.	Students set lathe gearing (or quick-change gearbox) for the specified threads-per-inch, grind or identify a 60° threading tool and set it to center height using a thread gauge, and complete a dry-run engagement of the half-nut at the correct position on the thread dial Students take multiple threading passes using the compound infeed method at 29°, advancing 0.002-0.005 in per pass for roughing and 0.001 in for finishing, checking with a thread pitch gauge every two passes and a 3-wire measurement on the finish thread Students tap the mating internal thread in the tailstock-held part using a bottom, plug, and taper tap set, then assemble external and internal parts and verify smooth hand fit; a thread ring gauge (GO/NO-GO) or calibrated 3-wire measurement is used as the final check	Engine lathe with quick-change gearbox or change gears, 60° HSS threading tool or carbide threading insert, thread pitch gauge set, 3-wire thread-measurement kit, thread micrometer or standard outside micrometer, tap set (taper, plug, bottom) in specified thread size, tap wrench, cutting oil, GO/NO-GO thread gauges for specified thread	External thread must pass GO gauge and reject NO-GO gauge; 3-wire pitch diameter measurement must be within the ASME B1.1 tolerance class 2A limits for the specified thread; mating assembly must thread smoothly by hand for full engagement — any failure requires re-machining a new blank
10	Knurling, Parting, and Drilling on the Lathe	10.5	lab	Students apply a uniform diamond knurl, part off a workpiece to length within ±0.010 in, and drill and bore a through-hole centered within 0.010 in TIR, all on a single part.	Students calculate the correct starting diameter for a 96-pitch diamond knurl using the formula (number of teeth on knurl wheel ÷ pitch) and turn the OD to that calculated diameter before applying the knurl tool at recommended slow speed with heavy cutting oil, tracking the double-diamond pattern Students part off the knurled section using a 1/16 in wide HSS parting blade at reduced spindle speed and slow cross-slide feed with consistent cutting oil application, measuring the parted length with a caliper Students center-drill, drill to near size, and bore a through-hole using a boring bar to the print diameter ±0.003 in, measuring with a telescoping gauge and outside micrometer; runout of the bore is checked with a dial indicator and test bar	Engine lathe, knurling tool (diagonal/diamond pattern, 96-pitch or as specified), HSS parting blade and toolholder, boring bar set, center drill, jobber drills, cutting oil (sulfurized or general-purpose), 6 in digital caliper, telescoping gauge set, outside micrometer, dial indicator	Knurl pattern must show complete, uniform diamond pattern with no tracking or skipping over at least 80% of the knurled length; parted length within ±0.010 in; bored hole diameter within ±0.003 in and bore runout within 0.010 in TIR — all three criteria must be met for a pass
11	Integrated Part: Reading Prints, Planning Operations, and Producing a Complete Part	19	practice	Given a multi-feature engineering drawing, students produce a complete part involving mill and lathe operations in a student-planned sequence, meeting all tolerances and documenting the entire process on a formal setup sheet.	Students receive a new, unseen drawing and independently complete a process plan listing each operation, machine, tooling, speed, feed, workholding method, and quality check point before beginning any machining — instructor reviews and approves the plan before cutting starts Students execute the approved process plan, producing the part across both the mill and lathe, measuring after each critical operation and recording actual dimensions on the inspection column of the setup sheet Students present the completed part and setup sheet to the instructor, who performs an independent dimensional check of every feature and asks the student to explain two setup decisions; student must correctly justify both decisions	Knee mill, engine lathe, full toolroom access (all tools covered in lessons 3-10), 6061 aluminum or 1018 steel stock as required by print, full set of measuring instruments, setup-sheet template aligned with NIMS Machining Level 1 documentation requirements	Every drawing feature must be within stated print tolerances confirmed by instructor measurement; setup sheet must be fully completed with no blank fields; student must correctly justify both setup decisions in the verbal review — one failed dimension or an incomplete setup sheet requires re-work and re-submission
12	NIMS Machining Level 1 Alignment: Review, Practice Test, and Credential Mapping	17	theory	Students map every skill practiced in this course to the applicable NIMS Machining Level 1 performance and written-test areas and correctly answer practice questions at or above the NIMS passing standard.	Students fill in a two-column NIMS crosswalk worksheet listing each NIMS skill area in one column and the corresponding lesson(s), lab part(s), or setup sheet in the other, identifying any gaps they feel need more practice Instructor leads a targeted review session addressing the three NIMS topic areas with lowest class-average scores from the crosswalk self-assessment, using worked examples drawn from NIMS sample items and the Machinery's Handbook Students complete a 40-question timed practice written exam modeled on NIMS Machining Level 1 question styles (safety, print reading, measurement, tooling, speeds and feeds, processes) and review wrong answers with a partner using the NIMS performance standards document	NIMS Machining Level 1 Performance Standards document (current version from nims-skills.org), crosswalk worksheet, Machinery's Handbook (current edition), NIMS-style practice question bank developed by the instructor, calculator	Students must score 80% or higher on the 40-question practice exam and have no gaps on the crosswalk worksheet (every NIMS skill area must cite at least one completed lab or setup sheet); students below 80% receive targeted remediation before the course ends

7	Lathe G-Code: Turning, Facing, Threading, and Grooving	16	demo	Students write G-code programs for a CNC lathe that produce a turned profile using G00, G01, G70/G71 stock-removal and finish cycles, a single-point thread (G76), and an external groove.	Instructor demonstrates G71 rough-turning cycle with live edits, then students copy the program into CNCSimulator Pro Lathe module, alter the stock dimensions, and re-run to observe how the cycle adapts. From a turned-part drawing with a shoulder, taper, and external thread, students write the complete lathe program in stages—facing, rough turn G71, finish turn G70, groove G75, thread G76—checking each stage in simulation before adding the next. Thread-parameter calculation exercise: given thread pitch, major diameter, and depth-of-cut per pass, students calculate G76 Q (first-pass depth), I (taper), and K (thread height) values before entering them into the simulator.	CNCSimulator Pro Lathe module; turned-part drawing; Haas lathe G-code reference; thread-parameter calculation worksheet; Smid Chapters 14–16	Simulated lathe program must run to completion without alarm; finished profile must match all drawing dimensions within 0.005 in. in simulation; thread parameters verified mathematically by instructor.
8	Tool-Length Compensation and Cutter-Radius Compensation	12	demo	Students apply G43/G44 tool-length compensation and G41/G42 cutter-radius compensation in G-code programs, correctly entering offset values so the simulated cutter follows the part profile at the correct depth and wall location.	Using a compensation-concept diagram, students manually calculate expected Z-position with G43 H-offset applied for three different tool lengths entered in the offset table, then verify in simulation. Write a contour program that intentionally omits G41, observe the resulting wall error in simulation, then insert G41 with the correct D-offset and document the dimensional change in a before/after comparison table. Offset-change drill: instructor secretly enters a wrong tool-length offset; students run the program in single-block mode in simulation, identify the Z-error symptom, locate the offset table entry, correct it, and re-run.	CNCSimulator Pro; compensation-concept diagram handout; offset-calculation worksheet; Haas operator manual Tool Offsets section; contour profile drawing	Before/after comparison table must show correct dimensional change matching the inserted offset value; offset-change drill completed with correct diagnosis and fix within 10 minutes; instructor sign-off required.
9	Safe Program Prove-Out on a Live Haas CNC Machine	18	lab	Students execute a safe, step-by-step prove-out sequence—lockout/tagout energy verification, single-block mode, 0% feed-rate override, dry run, air-cut—on a live Haas mill before engaging the first workpiece.	Complete a lockout/tagout demonstration on the Haas VF-2: isolate hydraulic and electrical energy, apply personal lock, verify zero energy with approved test method, then restore under instructor supervision before operating the machine—documented on a LOTO checklist. Load a pre-written student program into the Haas control via USB; run a full prove-out sequence using the shop's posted prove-out checklist (single-block on, FOV at 0%, dry run on, confirm all rapids clear fixtures, then air-cut at 25% feed); stop at any alarm and document the alarm code and corrective action. After a successful air-cut, increment feed-rate override to 100% in supervised increments of 25%, noting spindle load meter readings and comparing them to the calculated cutting power; record findings in a prove-out log sheet.

10	Editing, Debugging, and Optimizing G-Code Programs	14	lab	Students identify and correct syntax errors, logical toolpath errors, and inefficient rapid-move sequences in provided programs, then demonstrate the corrected program produces the intended feature in simulation.	Debug exercise: each student receives a program with five embedded errors (wrong modal group, missing decimal, incorrect arc direction, missing M-code, improper tool-change sequence); find and fix all five using the Haas alarm reference and G-code list within 30 minutes. Optimization challenge: take a working but inefficient 60-block program with redundant rapids and repeated coordinate values; reduce it by at least 15 blocks without changing the toolpath, using modal codes and variable repetition where legal. Edit a provided facing program to accommodate a 0.020 in. roughness allowance by adjusting the finish-pass depth of cut and feed rate, document the parameter changes, and confirm the edited program runs correctly in CNCSimulator Pro.	Printed and digital copies of three flawed programs; Haas alarm-code reference; CNCSimulator Pro; debug worksheet; optimization before/after record sheet	Debug exercise: all 5 errors identified and corrected within 30 minutes (100% required); optimization: block count reduced by ≥15 with toolpath unchanged, verified in simulation; instructor reviews and signs off each activity.
11	Setup Sheets, Program Documentation, and NIMS Standards	10	practice	Students produce a complete, industry-standard setup sheet and annotated program printout for a mill part program that satisfies NIMS program-documentation requirements.	Review a sample NIMS-compliant setup sheet and identify every required field (program number, material, workholding, tool list with offsets, datum location, inspection checkpoints); then complete a blank setup sheet for a provided finished program. Add inline comments (using parentheses notation) to a 40-block program so that every tool change, work-offset call, and canned-cycle activation is explained in plain English for the next operator; compare with a classmate and revise. Present the completed setup sheet and annotated program to a small peer group (3–4 students) in a 5-minute walkthrough, answering questions about tool selection and offset values as if orienting a new operator.	NIMS Machining Level 1 and Level 2 performance guides (setup documentation sections); sample setup sheet template; blank setup sheet form; annotated-program example; 40-block unannotated program	Setup sheet evaluated on a 10-item rubric (each field 0–2 points, 20 points total); must score ≥16/20 (80%); peer group confirms walkthrough is clear and complete with instructor observation.
12	Integrated G-Code Programming Project: Mill and Lathe Combination Part	20	lab	Students independently write, simulate, prove out, and run complete G-code programs for both a milled feature and a turned feature on a single combination part, producing dimensions within blueprint tolerance.	From a multi-view blueprint with both mill and lathe operations, students plan the operation sequence, calculate all coordinates, speeds, feeds, and canned-cycle parameters, then write the full G-code programs before touching any machine or simulator—planning packet submitted for pre-approval. After instructor approval of the planning packet, students simulate both programs in CNCSimulator Pro, run through the full prove-out checklist on the Haas VF-2 mill and Haas ST-10 lathe, execute supervised air-cuts, then machine the actual aluminum or low-carbon steel part. Inspect the finished part using calipers and a micrometer; record each measured dimension against the nominal and tolerance on an inspection report; identify any out-of-tolerance feature, diagnose the likely G-code or offset cause, and propose a corrective program edit.	Haas VF-2 CNC mill; Haas ST-10 CNC lathe; CNCSimulator Pro; aluminum 6061 or 1018 steel stock; combination-part blueprint; LOTO kit; cutting tools (end mill set, drill set, boring bar, turning insert, threading insert); 0–1 in. micrometer; 6 in. digital caliper; inspection report form	≥80% of blueprint dimensions within stated tolerance on first article; planning packet approved before machining; LOTO checklist signed by instructor; prove-out sequence completed without skipped steps—any step skipped requires full restart.

Pairs practice the Haas power-up sequence (main breaker → E-stop release → reference all axes) on live machines, recording each step on a laminated checklist. Students audit a machine with three planted deficiencies (low lube, damaged way cover, leaking coolant line), document findings, and verbally brief the class on corrective actions.	Haas VF-series mill and ST-series lathe, Haas Operator's Manual, pre-shift inspection checklist form, machine diagram worksheet, dry-erase markers	Student completes power-up and pre-shift inspection independently with zero omissions on the checklist; identifies all three planted deficiencies — 100% checklist accuracy required to advance.
2	Lockout/Tagout for CNC Environments	10	lab	Students write and execute a machine-specific LOTO procedure for a CNC mill and a CNC lathe that isolates all energy sources in compliance with OSHA 29 CFR 1910.147 before performing a simulated tooling change.	Students read the machine-specific energy-control program and identify all energy sources (electrical, pneumatic, hydraulic, stored spring) on a diagram; instructor reviews each source. Each student writes a machine-specific LOTO procedure from scratch, then has a peer audit it against the OSHA 1910.147 checklist before the instructor gives final approval. Students execute their approved LOTO procedure on the assigned machine, verify zero-energy state at each isolation point, perform a simulated tooling swap, and restore the machine to service — evaluated in real time by the instructor.	CNC mill, CNC lathe, LOTO station with padlocks and tags, OSHA 29 CFR 1910.147 standard excerpt, machine energy-control diagrams, LOTO procedure form	Student correctly identifies all energy sources, writes an approvable procedure, and executes LOTO with zero procedural errors observed in real time; any missed isolation point is an automatic fail requiring full repeat.
3	Workholding Selection and Vise Setup on the CNC Mill	16	lab	Students select appropriate workholding for three given part geometries, mount a precision machine vise on the mill table, and indicate the fixed jaw parallel to the X-axis to within 0.001 in over its full length.	Given three part drawings with differing shapes, students complete a workholding selection worksheet justifying vise, soft jaws, step clamps, or fixture plate for each; class discussion follows. Students disassemble, clean, and reinstall a Kurt-style vise on a T-slot table using proper torque sequence, then sweep the fixed jaw with a test indicator, adjusting until runout is within 0.001 in. Students clamp a steel block, verify seating with a rocking test (zero rocking on parallels), and re-indicate after clamping to confirm the jaw did not shift.	CNC mill, Kurt D688 vise or equivalent, T-slot hardware set, test indicator with magnetic base, torque wrench, steel parallels, workholding selection worksheet, part drawings	Fixed jaw indicated within 0.001 in TIR over full jaw length in two consecutive attempts; block passes rocking test — instructor verifies with own indicator sweep before signing off.
4	Cutting Tool Assembly and Presetting for the CNC Mill	14	lab	Students assemble five tool assemblies (face mill, end mill, drill, boring bar, tap) in CAT-40 holders, measure each tool length and diameter offset with a benchtop tool presetter, and record values on a standard tool list sheet.	Instructor demonstrates collet selection, torque procedure for ER collet nuts, and face-mill insert orientation; students assemble their own set of five tools following the demonstrated sequence. Each student measures tool length and radial runout on the presetter for all five assemblies, recording values on the tool list; runout must be within the tool manufacturer's spec before proceeding. Students compare presetter values to a feeler-gage manual touch-off on the machine, calculate the difference, and discuss sources of error in a brief written reflection.	CAT-40 tool holders (collet, shell mill arbor, drill chuck, boring bar holder), ER collet set, face mill with inserts, solid carbide end mill, jobber drill, boring bar, tap, torque wrench, benchtop tool presetter, tool list form, manufacturer spec sheets	All five tool length values recorded within 0.001 in of instructor-measured reference values; radial runout within manufacturer spec for each tool — instructor spot-checks two assemblies with presetter.
5	Tool Length and Diameter Offset Entry at the Haas Control	14	lab	Students enter tool length offsets for five tools into the Haas offset page using both the manual touch-off method and presetter-derived values, verify each entry against a reference gage block, and correct any entry error before program execution.	Using a 1-2-3 block as a reference surface on the mill table, students touch off Tool 1 manually (paper method), record the Z offset, then compare it to the presetter value from Lesson 4; instructor reviews technique. Students enter all five tool length offsets and two diameter offsets via the Haas offset page, double-checking each digit before pressing Enter; a peer verifies each numeric entry against the tool list. Instructor introduces a deliberate 0.200 in sign error in Tool 3's offset; students run a dry run, read the tool position display, identify the discrepancy, and correct the entry without instructor prompting.	Haas CNC mill with live control, 1-2-3 gage blocks, tool list from Lesson 4, Haas Operator's Manual (Offset section), offset entry worksheet	All five tool length offsets within ±0.001 in of instructor's verified reference values; student independently identifies and corrects the planted sign error during dry run — both criteria must be met.
6	Work Coordinate System Setup (G54–G59) on Mill and Lathe	14	lab	Students locate and set the work coordinate origin (G54) for a milled part using an edge finder and a lathe work offset (G54 Z) using a tool touch-off, entering all values at the control and verifying with a position readout check.	Students use a 0.200 in edge finder to locate the X and Y edges of a vise-held block on the mill, calculate the center offset, and enter the G54 X and Y values; instructor verifies by jogging to the nominal origin and reading the position display. On the lathe, students face a workpiece, touch off the facing tool at Z=0, enter the G54 Z offset, then verify by commanding G0 G54 Z1.0 in MDI and measuring the actual distance from the face to the tool tip with a rule. Students practice offsetting G55 for a second op on the same mill setup, enter the incremental shift, and document both work offsets on a setup sheet for handoff.	Haas CNC mill and lathe, 0.200 in edge finder, vise-held steel block, lathe chuck, facing tool, digital calipers, setup sheet form, Haas Operator's Manual (WCS section)	G54 X, Y (mill) and G54 Z (lathe) each within ±0.001 in of instructor-measured actual origin; MDI verification move matches commanded position within 0.002 in — both machines must pass.
7	Program Loading, Review, and Dry-Run Prove-Out	16	lab	Students transfer a 120-line NC program to the Haas control via USB and DNC, visually scan the code for critical errors using a program-review checklist, and execute a full dry run with feed-rate override at 5% and Z-axis raised 2.000 in, identifying all tool-path discrepancies before metal is cut.	Students transfer the provided G-code file via USB to the Haas control, then a second copy via DNC software; they verify file size and line count match the source file on both transfers. Using a program-review checklist, students scan the code for missing tool calls, absent M06, incorrect work offset calls, missing feeds and speeds, and unclosed loops; they annotate any finding on a marked-up printout. With Z raised 2.000 in and feed-rate override at 5%, students run the program in single-block mode, watching axis motion and comparing it to the tool path shown in Haas graphics mode, stopping to investigate any motion that differs from the expected path.	Haas CNC mill with USB port and DNC-capable network, G-code program file (provided), program-review checklist, USB flash drive, DNC software on instructor PC, program printout, feed-rate override dial	Student identifies all four planted program errors noted on the instructor answer key during the review checklist phase; dry-run completes without machine alarm and without the tool contacting the raised air-cut reference — both required.
8	Single-Block Cutting and In-Process Measurement	16	lab	Students execute a multi-operation milling program in single-block mode on a steel block, pause at designated checkpoints to measure an in-process feature with a micrometer and digital caliper, and adjust a wear offset to bring the next cut within tolerance before continuing.	Students run the first roughing pass in single-block at 50% feed override, pause after the roughing end mill retracts, and measure the pocket width with a 0–1 in micrometer; they record the measured value and calculate stock remaining. Based on the measurement, students calculate and enter a wear offset adjustment to hit the 1.000 ±0.002 in finish width, then run the finishing pass and re-measure; they document both measurements on the inspection log. After all operations complete, students measure the pocket depth with a depth micrometer and the hole diameter with a pin gage set, recording accept or reject disposition on the inspection log with objective numeric evidence.	Haas CNC mill, 1018 steel block, carbide end mill (roughing and finishing), 0–1 in outside micrometer, digital caliper, depth micrometer, pin gage set, inspection log form, wear offset procedure card	Finish pocket width 1.000 ±0.002 in and depth within print tolerance confirmed by instructor measurement; wear offset calculated and entered correctly with no overcut — any scrapped feature requires repeat with a new blank.
9	CNC Lathe Setup: Chuck, Tooling, and Turning Offsets	16	lab	Students mount a three-jaw chuck on the lathe spindle, install and touch off a turning tool and a boring bar in the turret, enter geometry offsets for both tools, and produce a turned diameter within ±0.002 in of the print dimension.	Students mount the three-jaw chuck, indicate the bore with a test indicator while tapping soft jaws to within 0.001 in TIR, and clamp a 2 in diameter 6061 aluminum bar; instructor checks runout before any cutting. Students install a CNMG turning insert and a boring bar in adjacent turret stations, touch off each tool's X and Z geometry offsets at the control using the razor-blade method, and record values on the tool list. Students run a facing pass, measure the faced length, then turn a 1.500 in diameter for 1.000 in length; they measure with a 0–2 in micrometer, apply a wear offset correction if needed, and finish-turn to 1.500 ±0.002 in.	Haas ST-series lathe, three-jaw chuck, CNMG insert turning tool holder, boring bar, 6061 aluminum 2 in round bar, 0–2 in outside micrometer, test indicator, digital caliper, tool list form, Haas lathe Operator's Manual	Turned diameter 1.500 ±0.002 in confirmed by instructor micrometer measurement; chuck runout ≤0.001 in TIR before cutting — both criteria required; overcut scrap mandates repeat.
10	Setup Documentation: Setup Sheets, Tool Lists, and Offset Records	10	theory	Students produce a complete, industry-standard setup package for an assigned mill part that contains a setup sheet with sketch, tool list with offsets, work offset record, and a process note section clear enough for a different operator to replicate the setup without asking questions.	Instructor presents three real-shop setup packages (one incomplete, one error-ridden, one exemplary); students compare them against a setup documentation standard and list deficiencies of the first two in writing. Students complete a full setup package for the mill part they set up in Lesson 8, using the shop standard forms; they include a freehand setup sketch showing vise jaw orientation, stock stick-out, and datum location. Pairs exchange completed setup packages and attempt to re-locate the workpiece datum on the machine using only the partner's documentation; any ambiguity is noted and the author corrects the document before final submission.	Setup sheet form, tool list form, work offset record form, sample setup packages (instructor-prepared), pencils, rulers, completed parts from Lesson 8, Haas control for verification	Completed setup package passes all items on the 20-point documentation rubric (setup sketch, tool list with holders and offsets, WCS values, process notes); peer replication test succeeds without verbal clarification — 18/20 minimum.
11	First-Article Inspection and Part Disposition	14	lab	Students measure every print-specified feature on a first-off part using the correct gaging for each feature type, record results on a first-article inspection (FAI) form, and make a documented accept, rework, or scrap disposition based solely on the measured evidence.	Instructor distributes a part drawing with eight specified features (two diameters, one bore, two lengths, one surface finish, one angular chamfer, one thread); students identify the correct gage for each feature before measuring begins. Students measure all eight features on their first-off part, recording nominal, tolerance, and actual values on the FAI form; they apply GO/NO-GO gages to the thread and bore as appropriate. Students write a disposition statement for each out-of-tolerance feature (rework path or scrap reason) and discuss total decisions as a class; instructor reveals true values from a CMM report for comparison.	First-off milled or turned part (from Lesson 8 or 9), part drawing, FAI form, 0–1 in and 1–2 in outside micrometers, digital calipers, telescoping gage set, bore gage, surface roughness comparator, GO/NO-GO thread gage, protractor, CMM report (instructor reference)	All eight feature measurements within ±0.001 in of CMM reference values; disposition on each feature matches CMM-based ground truth; FAI form fully completed — 7 of 8 features correctly measured and correctly dispositioned required to pass.
12	Integrated CNC Setup Practical: Cold Machine to Verified First Part	18	lab	Working from a setup package and part drawing issued at the start of the session, students independently complete every step from LOTO and machine inspection through workholding setup, tooling, offset entry, prove-out, cutting, and FAI, producing a conforming first part within the allotted time.	Each student receives a sealed setup package and part drawing; they plan their sequence, perform LOTO and pre-shift inspection, mount workholding, and indicate the vise — all before the instructor signs the LOTO release to proceed. Students install and preset all required tools, enter all geometry and work offsets, load the provided NC program, and conduct a full dry-run prove-out with a signed dry-run checkpoint log before any metal is cut. Students cut the part, perform in-process measurements at designated checkpoints, apply any necessary wear offset corrections, and complete the FAI form; they submit the part, all documentation, and the setup package to the instructor for final evaluation.	Haas CNC mill or lathe (assigned), all tooling and workholding required by the setup package, part drawing, setup sheet, FAI form, LOTO station, full gage kit (micrometers, calipers, bore gage, thread gages), raw stock	All print-specified features within drawing tolerance confirmed by instructor measurement; LOTO executed without error; FAI form complete and accurate; full setup completed within the allotted session time — any single out-of-tolerance feature or LOTO violation is a fail requiring a full repeat practical.

3	Vernier, Dial, and Digital Calipers	14	lab	Students measure outside diameter, inside diameter, depth, and step dimensions with vernier, dial, and digital calipers and record readings that agree with a lab standard within the instrument's rated accuracy.	Read and record 30 pre-set vernier caliper positions shown on laminated training cards before touching the real instrument—builds reading skill without tool wear. Measure outside diameter, bore, groove depth, and step height on a machined practice part with all three caliper types; tabulate results side by side and identify any discrepancies. Zero and re-zero a digital caliper ten times, then measure the same gauge block stack; record the spread to demonstrate repeatability and discuss what causes variation.

5	Dial Indicators, Test Indicators, and Surface Plates	14	lab	Students set up dial and test indicators on magnetic-base stands over a surface plate to measure runout, flatness deviation, and part-to-surface-plate squareness on assigned workpieces.	Set up a dial indicator on a granite surface plate to sweep a flat reference surface; record readings at a 9-point grid and calculate flatness deviation; compare to drawing callout. Mount a cylindrical part between centers (or in a V-block) and measure total indicated runout (TIR) at two axial positions; record on an inspection report and interpret against a GD&T runout callout. Use a test indicator to align a square workpiece parallel to the surface plate and verify squareness of a side face with a precision square; document the setup with a sketch.

Instructor observation: student correctly sweeps flatness and reports TIR within ±0.0002 inch of instructor-measured value; documented inspection report signed; pass = both measurements within tolerance and report complete.
6	Gauge Blocks: Calibration, Wringing, and Use	10	demo	Students select, wring, and verify gauge block stacks that build target dimensions to within 0.000050 inch, and explain the care and calibration cycle requirements for shop-grade blocks.	Instructor demonstrates the wring technique on a Grade 2 set; students then wring four pairs and test adhesion by attempting to slide the blocks apart—confirm correct technique. Given five target dimensions (from a worksheet), students choose the minimum number of blocks from a 81-piece set, build the stacks, and verify with a digital height gauge. Inspect a set of practice blocks for burrs, corrosion, and wear using a loupe and optical flat demonstration; categorize each block as serviceable or needing calibration.	81-piece Grade 2 gauge block set, optical flat (for demonstration), digital height gauge, loupe, cleaning cloth, gauge block selection worksheet, care and calibration reference card.	Student builds three assigned stacks; each must be within ±0.000050 inch of the digital height gauge reference; pass = all three within tolerance.
7	Functional Gauging: Go/No-Go and Fixed Gauges	12	lab	Students apply go/no-go plug gauges, ring gauges, and snap gauges to accept or reject machined parts for diameter and thread conformance, and record decisions on inspection forms with reference to the underlying tolerance.	Using a set of go/no-go plug gauges, inspect 20 bored holes on sample parts (some deliberately out of tolerance) and record accept/reject decisions; compare with micrometer measurements to reconcile any apparent discrepancy. Inspect external threads on ten sample bolts using thread ring gauges; cross-check two of them with a thread-pitch gauge and optical comparator (or thread-measuring wires if comparator unavailable). Discuss and document the Taylor principle of gauging: explain in writing why the go gauge must enter fully and the no-go gauge must not—relate to MMC and LMC concepts from the GD&T course.

8	Surface Finish Measurement and Interpretation	10	theory	Students interpret surface finish symbols on engineering drawings and measure Ra and Rz on machined samples using a contact profilometer, comparing results to print callouts.	Match surface finish symbols and values (drawn from ASME Y14.36M) to a set of visual/tactile comparator chips; rank them coarsest to finest and explain what machining process typically produces each. Run a contact profilometer across three machined test samples (milled, turned, ground); record Ra values and compare them to the drawing callouts provided by the instructor. Explain in a short written paragraph how cutting speed, feed rate, tool nose radius, and coolant affect surface finish, drawing on experience from the Manual Mill & Lathe course.	Contact profilometer (surface roughness tester), machined test samples, surface finish comparator set, engineering drawings with finish callouts, ASME Y14.36M surface texture reference (abridged), profilometer operating manual.	Student measures Ra on two samples and selects the correct accept/reject decision based on the print callout; written paragraph is coherent and technically accurate; pass = both measurements correct and paragraph accepted by instructor.
9	GD&T Verification at the Surface Plate	16	lab	Students verify parallelism, perpendicularity, concentricity/coaxiality, and position tolerances on machined parts using surface plate setups and document findings on a full GD&T inspection report.	Set up a machined prismatic part on parallels; use a dial indicator to sweep two faces and calculate parallelism error; compare to the tolerance frame on the print. Inspect cylindrical concentricity by mounting a part on a mandrel between centers over the surface plate; measure TIR at each referenced diameter and determine if the geometric tolerance is satisfied. Complete a full GD&T inspection report for a four-feature part (flatness, parallelism, perpendicularity, and runout); present findings verbally as if reporting to a quality engineer.	Granite surface plate, dial and test indicators, height gauge, angle plate, V-blocks, mandrel set, precision parallels, sine bar, machined inspection parts with GD&T-annotated drawings, ASME Y14.5-2018 reference (abridged), inspection report template.	Completed GD&T inspection report reviewed by instructor: all four features measured, values within ±0.0002 inch of instructor standard, accept/reject decisions correct; pass = all four features correctly evaluated.
10	Coordinate Measuring Machine (CMM): Operation and Programming Basics	20	lab	Students operate a CMM under supervision to probe a minimum of six features on a prismatic part, align the part using a datum reference frame, and generate a printed inspection report from the CMM software.	Walk through CMM startup, homing, probe qualification on the reference sphere, and safe joystick movement; each student performs startup and probe qualification under direct instructor supervision. Program and run a manual or CNC CMM routine to measure three diameters, two planes, and one position feature on a practice part; record all nominal, measured, and deviation values. Interpret the CMM printout against the part drawing and fill in a pass/fail column for each feature; discuss with the instructor any out-of-tolerance condition and identify likely machining cause.	Bridge-type CMM (manual or CNC), probe qualification sphere, CMM software (e.g., PC-DMIS or equivalent), prismatic inspection parts with drawings, CMM operating manual, inspection report template, personal protective equipment (safety glasses).	CMM inspection report for a six-feature part produced independently (with supervisor present for safety); measured values must agree with instructor-run baseline within CMM-rated repeatability; pass = report complete and accepted/rejected decisions correct for all six features.
11	Statistical Process Control and First-Article Inspection	18	lab	Students complete a first-article inspection (FAI) report for a machined part and construct a basic X-bar and range (X̄-R) control chart from a provided data set, identifying whether the process is in statistical control.	Measure all dimensions called out on a first-article part print (minimum ten dimensions); record results on an AS9102- or PPAP-style FAI form and determine overall part disposition. From a provided data set of 25 subgroups of five measurements, calculate subgroup means and ranges, plot an X̄-R chart by hand, add control limits, and identify any out-of-control signals using the standard Western Electric rules. Discuss as a class: if a control chart shows the process drifting toward the upper control limit, what measurement, tooling, or machine adjustments could bring it back in control?	Machined first-article sample part with dimensional drawing, FAI report form, SPC data worksheet, graph paper or SPC software, calculator, AIAG SPC reference guide (abridged), Machinery's Handbook.	FAI report complete and disposition correct; X̄-R chart plotted with correct limits and at least one out-of-control point correctly identified; pass = FAI 100% complete and chart limits within ±5% of calculated values.
12	Calibration Awareness, Measurement System Analysis, and Capstone Inspection Exercise	20	lab	Students demonstrate the complete shop measurement workflow—instrument selection, zeroing and calibration check, measurement, SPC data entry, and inspection report—on an unknown part under timed, exam-like conditions.	Perform a gage R&R (repeatability and reproducibility) exercise on one critical diameter: three operators each measure ten parts twice; enter data into a provided template and calculate %GR&R; discuss whether the measurement system is adequate for the tolerance. Given an unknown machined part and its drawing, each student independently selects instruments, measures all callout dimensions, completes an inspection report, and presents findings to the instructor—simulating a job-shop quality check. Review facility gage recall procedures: students trace a mock calibration tag on a micrometer, determine if it is past its calibration due date, and follow the written procedure to quarantine and tag the instrument.	Unknown machined parts (instructor-selected), complete instrument set (calipers, micrometers, indicators, surface plate), gage R&R worksheet, mock calibration tags and quarantine labels, gage recall procedure SOP (facility or simulated), inspection report forms, NIMS Measurement, Materials & Safety competency checklist.	Complete independent inspection report accepted by instructor; %GR&R calculated correctly; gage recall procedure followed without prompting; pass = inspection report disposition correct, %GR&R within ±5% of instructor value, and recall procedure executed correctly.

Lessons · 4 blocks

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Project Planning and Process Engineering	36	theory	Given an instructor-issued engineering drawing of a multi-feature part, the student produces a complete process plan including operation sequence, machine assignments, workholding strategy, tooling list, cutting parameters, and estimated cycle time before any material is cut.	Interpret the capstone drawing as a class: students mark all GD&T callouts, identify datums, flag the three tightest tolerances, and write a brief 'inspection risk' note for each critical feature on a printed markup sheet Working individually, students draft a process plan on the program-standard Process Planning Worksheet, sequencing roughing, semi-finishing, and finishing operations across mill and lathe setups, and calculating spindle speed and feed rate for each tool using the cutting-speed formulas from Course 1 math and Course 6 setup notes Peer-review in pairs: each student reviews their partner's tooling list against the shop's actual available tooling, flags any substitutions needed, and signs off or writes a corrective comment; instructor resolves disputes and approves final plans before any CAM work begins	Capstone engineering drawing (instructor-issued, multi-feature, includes GD&T), Process Planning Worksheet template, Machinery's Handbook (current edition), shop tooling catalog, calculators, Haas control reference card, NIMS Machining L1 Process Planning study guide	Instructor reviews completed process plan using the Capstone Process Plan Rubric; plan must earn at least 80% across categories: drawing interpretation accuracy, operation sequence logic, tooling appropriateness, and parameter calculations within ±10% of instructor-verified values; plans below 80% are revised within one session before student advances
2	CAM Programming, G-Code Verification, and Setup Documentation	54	lab	The student programs the complete capstone part in Mastercam, post-processes verified G-code for the shop's Haas control, and produces finalized setup sheets and tool offset sheets that a second person could use to run the job without additional verbal instruction.	Students model or import the 2D drawing geometry into Mastercam, assign stock, and build toolpaths for each operation from the approved process plan; instructor checkpoints are required at: stock definition, first roughing toolpath, and final finish toolpath before post-processing is permitted — each checkpoint is initialed on the student's checklist Post-process the verified Mastercam file to a Haas-compatible NC file; open the G-code in a text editor and in the Haas simulator or Vericut (where available), perform a dry-run cycle time check, and annotate the code printout highlighting work offset calls (G54–G59), tool change blocks, and any canned cycles used — students correct any alarms or collisions before signing off Complete the Setup Sheet Package: one page per setup, showing machine, vise/fixture jaw position and torque, part zero location with a sketch, tool list with offset columns, and any special notes; additionally write a one-paragraph 'first-article checklist' describing the five measurements to confirm before running full production	Mastercam (current version licensed on lab workstations), Haas post-processor, Haas Mill and Lathe Operator Manuals, Vericut or Haas simulation mode, Setup Sheet template, G-code annotation worksheet, Mastercam Associate certification study guide, USB or DNC transfer cable	Instructor and a peer independently attempt to set up the machine using only the student's setup sheet package (no verbal help from the student); setup must be achievable with zero requests for clarification; G-code simulation must show zero collisions and a cycle time within 15% of the student's estimate; Mastercam toolpath file is evaluated against the Mastercam Associate exam competency checklist — minimum 80% of checklist items satisfied
3	Machine Setup, Production Run, and In-Process Inspection	90	practice	The student performs a complete LOTO procedure, sets up the Haas mill and/or lathe per their own setup sheets, executes a single-block dry run, machines the part from raw stock through all operations, and records in-process measurements on an inspection log at each critical stage.	Before touching any machine: perform and document full lockout/tagout in writing on the LOTO Verification Form, don correct PPE (safety glasses, chip shield, steel-toed footwear), load tools in correct holders to torque spec, establish work offset using an edge finder or probe, and enter all tool length offsets; instructor observes and signs the LOTO form — failure to complete LOTO correctly stops the student and requires a full restart Execute a single-block dry run at 5% rapid override with hands on feed-hold; annotate any discrepancies on the G-code printout; once cleared by instructor, run first article at reduced feedrate override (60%), stop after each operation, and measure all features called out on the First-Article Checklist before proceeding; record all readings on the Inspection Log using the correct instrument (micrometer, caliper, height gage, CMM if available) and note any out-of-tolerance conditions immediately Complete remaining operations; if an out-of-tolerance condition is found during in-process inspection, the student completes a Nonconformance Report (NCR) identifying the dimension, actual vs. nominal, probable cause, and proposed corrective action before cutting resumes; instructor must approve the corrective action; all chips and coolant are cleaned up per shop housekeeping SOP at the end of each shift	Haas CNC mill and/or lathe, approved raw stock (aluminum 6061 or 1018 steel per drawing), LOTO locks and tags, LOTO Verification Form, cutting tools per approved tooling list, edge finder or Renishaw probe, digital calipers (0.0005 in resolution), outside micrometers (0.0001 in), depth micrometer, height gage, surface plate, gage blocks, Inspection Log form, Nonconformance Report form, shop safety glasses, chip shield, PPE station, Haas Certification competency checklist	All critical dimensions on the finished part are measured by the instructor independently using calibrated instruments; each critical dimension must be within the drawing tolerance — zero critical dimensions out of tolerance for a passing part; LOTO Verification Form must be complete and signed; Nonconformance Reports (if any) must be complete and logical; any student who bypasses LOTO or removes a guard receives an automatic fail and must restart after a remediation session
4	Documentation Completion and Project Defense	36	field	The student assembles a complete project portfolio and delivers a 20-minute oral defense to a panel of at least one instructor and one industry evaluator, explaining every major decision made during the project and responding to at least five technical questions without reference to notes.	Students assemble the final Project Portfolio binder (physical or digital per school policy) containing: the annotated engineering drawing, approved process plan, Mastercam setup screenshots and toolpath backplot images, final G-code printout with annotations, setup sheet package, completed inspection log with measured values entered alongside nominal dimensions and tolerances, all Nonconformance Reports, and a one-page written 'Lessons Learned' reflection identifying at least two specific improvements to process, tooling, or parameters supported by the inspection data Students prepare and deliver a 20-minute structured oral defense presentation (slides or whiteboard permitted) covering: part overview and drawing interpretation, process planning rationale, CAM strategy and post-processor choices, setup decisions and LOTO steps, in-process inspection results, any NCRs and corrective actions, and proposed improvements — evaluators score each section on the Capstone Defense Rubric in real time Evaluator question period (minimum 10 minutes): the panel asks at least five questions drawn from the Capstone Defense Question Bank, which covers topics mapped to NIMS L1–L2 process planning and quality control areas, Mastercam Associate toolpath and post-processor competencies, and Haas Certification setup and operation competencies; student answers from memory and may refer only to their own finished part and measurement data physically present on the table	Finished capstone part, complete Project Portfolio, Capstone Defense Rubric, Capstone Defense Question Bank (instructor-held), projector or whiteboard, evaluation panel score sheets, finished part with all surfaces visible for handling during Q&A	Evaluator panel scores the defense using the Capstone Defense Rubric across five domains: portfolio completeness, technical accuracy of explanations, quality of corrective action reasoning, communication clarity, and response quality under questioning; student must earn 80% overall and no domain below 70% to pass; any domain below 70% triggers a targeted re-defense of that domain within two weeks

Assessments

Assessment	Type	Weight	Pass standard	Method & rubric
Finished Capstone Part with Inspection Report	Project	60%	All critical dimensions within drawing tolerance as measured by instructor with calibrated instruments; Inspection Log complete with actual values recorded for every dimension on the drawing; zero critical nonconformances on finished part; LOTO Verification Form complete and signed for every setup	The physical machined part is the primary project evidence; the instructor independently measures all features called out on the drawing and compares them to the student's own inspection log to verify both part quality and measurement accuracy. An incomplete or unsigned LOTO form, or any critical dimension outside tolerance, constitutes a failing condition requiring the student to machine a replacement part from new stock. Meets specification · Within estimate · Workmanship · Safety · Documentation
Project Portfolio	Portfolio	20%	Portfolio scored at 80% or higher on the Portfolio Completeness and Quality Rubric; all eight required sections present; Lessons Learned reflection cites at least two specific, data-supported improvements; Nonconformance Reports (if any) complete with root cause and corrective action	The portfolio is evaluated as a professional work document — the standard applied is whether an experienced machinist picking up the binder could fully understand what was planned, what was done, what was found, and what would be changed on the next run. Missing sections, unsupported claims, or inspection logs with blanks where measurements should appear each reduce the score proportionally on the rubric. Completeness · Organization · Evidence quality
Oral Defense	Oral / panel	20%	Overall score of 80% on the Capstone Defense Rubric with no individual domain below 70%; student must answer at least four of five panel questions correctly and completely without reference to notes; use of finished part and personal inspection data as physical reference is permitted	The oral defense simulates an industrial first-article review meeting and is scored by a panel of at least one instructor and one industry evaluator using a structured rubric mapped to NIMS Machining L1–L2 process planning and quality competencies, Mastercam Associate toolpath and post-processing competencies, and Haas Certification setup and operational competencies. Students who score below the threshold in one domain complete a targeted re-defense of that domain only; students who score below 80% overall repeat the full defense after additional preparation time.

Conduct in-process inspection at supervisor-directed intervals using shop calipers, micrometers, and gauges; record measurements on the shop's inspection form and flag any out-of-tolerance condition immediately to the supervisor, documenting the corrective action taken. Participate in or observe at least two tool-life management cycles (identifying worn inserts, selecting replacements from the crib, updating offsets) and document the process, tool grade, and measured surface-finish outcome in the field log.	Employer's CNC mill and/or lathe (Haas or equivalent), work-holding hardware, cutting tools and inserts, shop blueprints, shop inspection forms, digital calipers, outside micrometer set, surface-finish comparator, field log notebook, NIMS Machining Level 1–2 skills standards checklist.	Supervisor initials each field log entry within 48 hours of completion; ≥ 10 of 12 documented jobs show first-article parts within print tolerance; no unaddressed safety incident during this phase.
3	Mid-Point Employer Evaluation and Goal-Setting Conference	8	field	Student receives a structured mid-point evaluation from the site supervisor, identifies at least two areas for improvement, and co-writes a written action plan with specific, measurable goals for the second half of the placement.	Supervisor completes the program's standardized mid-point evaluation form rating the student on safety compliance, technical skill, work quality, attendance and punctuality, communication, and initiative using a 1–4 scale; student reviews ratings with supervisor in a face-to-face conference. Student self-evaluates using the same form independently before the conference, then compares self-ratings to supervisor ratings and discusses any significant gaps, focusing on root cause rather than justification. Student and supervisor co-write a one-page action plan identifying two to three specific improvement goals, the on-the-job activities that will address them, and success criteria measurable before the final evaluation; program coordinator countersigns the plan.	Program mid-point employer evaluation form, student self-evaluation form, action plan template, field log to date, program coordinator contact information.	Completed and countersigned mid-point evaluation form and action plan submitted to program coordinator within five business days of the conference; composite mid-point rating of 2.0 or higher on the 4-point scale is required to continue placement without a remediation meeting.
4	Final Employer Evaluation, Field Log Completion, and Exit Debrief	92	field	Student completes remaining production assignments, finalizes the 12-entry field log with full documentation, receives the final employer evaluation, and participates in an exit debrief that produces a self-assessment connecting externship experience to NIMS, Mastercam Associate, and Haas Certification exam readiness.	Complete any remaining production setups or special assignments identified in the mid-point action plan; ensure all 12 field log entries are fully written up, legible, and include a supervisor initial before the final week of placement. Supervisor completes the final employer evaluation form using the same 1–4 rubric; student and supervisor hold a 30-minute exit debrief reviewing growth from mid-point, discussing employment prospects, and identifying remaining skill gaps to address in the Certification Exam Preparation course. Student writes a two-page reflective summary connecting at least five specific on-the-job experiences to credential exam knowledge areas (NIMS L1-2 job planning and tool selection, Haas machine operation, or Mastercam toolpath verification) and submits it along with the signed final evaluation and complete field log to the program coordinator.

#	Lesson	Hr	Type	Objective	Activities	Materials	Check
1	Diagnostic Assessment & Targeted Gap Analysis Across All Three Credentials	12	theory	Students complete a full-length diagnostic practice exam for each credential—NIMS L1/L2, Mastercam Associate, and Haas Certification—and use scored results to build a personal remediation plan prioritizing weak domains.	Take a 60-question timed NIMS Machining L1/L2 written diagnostic covering blueprint reading, GD&T, speeds and feeds, tolerancing, and quality control; self-score using the NIMS domain breakdown sheet and record percent correct per domain. Complete a Mastercam Associate diagnostic task set—stock definition, 2D contour and pocket toolpaths, 3D surface finish toolpath, and code post—then compare output to the published Mastercam Associate task rubric and note every missed criterion. Work through a Haas Certification diagnostic scenario on the Haas CNC Simulator (or live Haas mill/lathe): navigate to the Offset page, enter tool-length and wear offsets, run a dry cycle with block delete active, and recover from a simulated alarm; instructor scores each step against the Haas exam checklist.	NIMS Machining L1 and L2 study guides and domain blueprints (NIMS.org); Mastercam Associate Certification Guide and sample task files (CNC Software, LLC); Haas Certification study materials and CNC Simulator software (Haas Automation); blank personal remediation log forms; computers with Mastercam educational license; Haas CNC Simulator or live Haas mill and lathe.	Each student submits a scored diagnostic report for all three credentials and a completed remediation plan identifying at least three priority domains with specific study actions; instructor reviews plans for accuracy and completeness before the next lesson—no numeric pass threshold; completion and quality of plan are evaluated on a go/no-go rubric.
2	NIMS Machining L1 & L2 Domain Review and Performance Skill Practice	28	lab	Students achieve at or above the NIMS passing standard on all NIMS blueprint domains by working through targeted written-item banks and completing hands-on performance tasks that mirror NIMS credentialing-activity requirements.	Rotate through six NIMS domain stations (measurement and quality control; print reading and GD&T; milling operations; turning operations; CNC operations; workplace safety and material properties), spending approximately 40 minutes per station completing 20 timed practice items per station drawn from the NIMS item bank, then discussing missed items with a peer reviewer using the NIMS domain explanations. Perform two NIMS-style performance skill tasks on the manual mill and CNC lathe—each task specifies a drawing with tolerances of ±0.002 in or finer, requires selection of speeds and feeds from a machining handbook, and culminates in full first-article inspection with a coordinate measuring tool or micrometer; record all measurements on a NIMS performance task sheet and self-assess against the NIMS tolerance criteria. Complete a 45-minute written timed practice exam of 80 NIMS-format questions under test conditions (no notes, instructor proctored), score immediately, enter results into the remediation log, and spend the remaining time in directed remediation using NIMS study guide sections matched to missed items.	NIMS Machining Level 1 and Level 2 study guides; NIMS practice item banks (school NIMS Center or NIMS-provided materials); manual mill, CNC lathe, and associated tooling; 6-inch digital calipers, 0–1 in micrometer, depth micrometer, dial test indicator; machining handbooks (Machinery's Handbook); part drawings with GD&T callouts; personal remediation logs.	Students must score at or above the published NIMS passing threshold (currently 70% or higher per NIMS policy—confirm with current NIMS guidelines) on the timed 80-question written practice exam AND meet all dimensional tolerances on both performance skill tasks before this lesson is marked complete; students below threshold receive one structured remediation session and one retest attempt within the lesson block.
3	Mastercam Associate & Haas Certification Domain Review and Timed Task Practice	28	lab	Students demonstrate proficiency across all Mastercam Associate exam task areas and all Haas Certification tested competencies by completing timed, graded practice tasks that replicate the format and pass criteria of each vendor exam.	Complete three Mastercam Associate-format CAM tasks of increasing complexity in timed sessions: Task 1—2D part with contour, pocket, drill, and facing toolpaths, correct stock and material setup, and a posted G-code file reviewed for errors; Task 2—3D surface model with a scallop-height-controlled finishing toolpath; Task 3—a multiop part requiring tool-change logic, feed optimization, and collision checking; each task is scored against the published Mastercam Associate rubric for toolpath correctness, parameter selection, and code validity. Work through Haas Certification review stations covering: machine power-on and reference return procedure; MDI mode operation; tool-length offset measurement and entry using a tool-setter; work coordinate system setup (G54–G59); program search, editing single blocks, and inserting a dwell; alarm identification and appropriate response; each station ends with a pass/fail skills check against the Haas exam competency list. Pair up for peer mock evaluations: one student acts as examiner using the Mastercam Associate or Haas checklist while the other performs the task under timed conditions; partners then swap roles, debrief using the rubric, and each student records results and corrective notes in their remediation log.	Computers with Mastercam educational license (current version matching Mastercam Associate exam version); Mastercam Associate Certification Guide and sample part files (CNC Software, LLC); Haas CNC Simulator software and/or live Haas VF-series mill and ST-series lathe; Haas Certification study guide and competency checklist (Haas Automation); tool-height setter; offset sheets; personal remediation logs; stopwatch or timer.	Each Mastercam task must earn a passing score per the Mastercam Associate rubric (confirm current pass percentage with CNC Software); all Haas station skills checks must receive a pass rating from the instructor using the Haas competency checklist; any fail requires one targeted remediation exercise and one recheck before the lesson is marked complete.
4	Full-Length Timed Mock Exams, Remediation, and Exam Registration Verification	22	practice	Students pass full-length, timed mock versions of all three credential exams under proctored exam conditions and complete all administrative steps—registration, ID verification, and fee payment—required to sit the live credentialing exams.	Sit three consecutive full-length mock exams in proctored, timed, closed-note conditions: (1) an 80-question NIMS Machining L1/L2 written mock exam using the NIMS domain blueprint weightings; (2) a complete Mastercam Associate mock task set timed to match the published exam window; (3) a Haas Certification mock covering all tested machine-control competencies on the Haas Simulator or live machine; instructor scores all three immediately and returns results with a domain breakdown. Use scored mock results for a final 4-hour targeted remediation block: students below passing on any domain complete instructor-assigned practice items, re-machine a tolerance-critical feature, or re-execute a Haas control procedure, then complete a short recheck task to confirm improvement before the course ends. Verify and finalize all exam registration logistics: confirm NIMS online testing account and scheduled test date; confirm Mastercam Associate exam registration through the Certiport or authorized testing portal; confirm Haas Certification enrollment through the school's Haas Technical Education Center coordinator; assemble exam-readiness portfolio (mock scores, remediation log, registration confirmations, government-issued ID copy) and present it to the instructor for final sign-off.	Full-length NIMS mock exam (NIMS-provided or school-developed to NIMS blueprint); Mastercam Associate full mock task files; Haas Certification mock competency checklist; computers with Mastercam license; Haas Simulator or live Haas machine; NIMS online testing portal access; Certiport or authorized Mastercam testing portal; Haas TEC coordinator contact; personal remediation logs; exam-readiness portfolio binder or digital folder.	Students must score at or above the current published passing threshold for each credential on the full-length mock exam AND have confirmed registration for all three live credentialing exams before receiving a course completion sign-off; any student below passing on a mock exam completes the structured remediation recheck and must reach passing on that recheck to proceed to the live exam.
