ADM Problem 4.3.5

Aerospace Component CNC Manufacturing Challenge

Use Fusion and Mach3 to set up the DMC2 Mini, manufacture the approved component, inspect it, complete a fit test, and defend the process.

Learning targets

Today You Will Learn To

  • Complete a supervised CNC setup and dry run.
  • Manufacture and inspect the approved component.
  • Use dimensional and fit evidence to recommend a process or design revision.
Manufacturing context

Why This Matters

This challenge connects the complete classroom workflow: aerospace requirements, Fusion CAD, Fusion Manufacture toolpaths, Mach3Mill post processing, Mach3 verification, supervised DMC2 Mini machining, dimensional inspection, interface fit testing, and process revision.

Educational prototype

Aerospace Application Boundary

This component is an educational manufacturing prototype. It is not approved for installation on a crewed aircraft, operational aircraft, or flight-critical system. Any real aerospace application would require additional engineering analysis, material certification, process control, inspection, documentation, and regulatory approval.

Learning sequence

Learn Before You Build

Complete these steps in order. Record the requested notes or evidence before moving to the graded activity.

Full class period

Day 1 — Production readiness

Review the complete digital thread from mission requirements through CAD, drawing, CAM, simulation, posted code, setup sheet, and inspection plan.

Full class period

Day 2 — Setup and dry run

Observe the teacher model for workholding, work zero, tool setup, program preview, raised-Z run, and stop conditions on the assigned machine.

Full class period

Day 3 — Controlled machining

Review operator roles, observation zones, feed hold, emergency stop, chip control, and production-log expectations.

Three class periods

Days 4–6 — Inspect, fit, improve, defend

Learn how dimensional evidence, fit testing, nonconformance records, and revision decisions determine whether the prototype is accepted.

Detailed activity procedure

Complete the Six-Day Aerospace Component CNC Manufacturing Challenge

  1. 1
    DAY 1 — Freeze the approved Fusion design revision. Verify that the technical drawing, requirements table, prototype disclaimer, stock plan, tool list, setup sheet, and inspection plan all reference the same revision.
  2. 2
    DAY 1 — Review the complete Fusion setup, operation order, tools, cutting parameters, heights, workholding clearance, simulation, warnings, and estimated cycle time.
  3. 3
    DAY 1 — Post the approved setup using the machine-specific pathway. DMC2 Mini uses the teacher-validated Mach3Mill workflow; FoxAlien uses the exact-model controller and teacher-selected post.
  4. 4
    DAY 1 GATE — Complete the Production Readiness Checklist and receive written teacher approval.
  5. 5
    DAY 2 — Inspect the assigned machine, stock, tool, collet/holder, workholding, fixture, and emergency-stop access.
  6. 6
    DAY 2 — Secure and align the stock using the approved method. Record the stock dimensions and workholding locations.
  7. 7
    DAY 2 — Complete the approved reference/startup process, establish the work zero, and verify the tool reference.
  8. 8
    DAY 2 — Load the approved NC file and compare the controller preview with the approved Fusion simulation.
  9. 9
    DAY 2 — Complete the raised-Z, air-cut, or single-block dry run. Verify direction, extents, depth range, clearances, spindle method, feed override, and final position.
  10. 10
    DAY 2 GATE — Obtain authorization to begin material cutting.
  11. 11
    DAY 3 — Start the program at the teacher-approved reduced feed or first-cut condition.
  12. 12
    DAY 3 — Observe continuously from the approved location. Record program start, tool behavior, sound, vibration, chips, pauses, feed changes, interventions, and any nonconformance.
  13. 13
    DAY 3 — Stop immediately for loose workholding, incorrect direction, excessive vibration, tool damage, unexpected depth, collision risk, or any unclear condition.
  14. 14
    DAY 3 — Complete the approved shutdown, part removal, machine cleaning, and tool inspection.
  15. 15
    DAY 4 — Deburr and finish only with approved tools. Preserve all features needed for inspection.
  16. 16
    DAY 4 — Inspect every critical feature using the specified measuring tool. Record target, lower limit, upper limit, measured value, error, and pass/fail status.
  17. 17
    DAY 4 — Repeat selected measurements to check consistency and identify any result close to a tolerance limit.
  18. 18
    DAY 4 — Create a nonconformance report for every failed feature instead of altering or hiding the result.
  19. 19
    DAY 5 — Complete the airframe-interface, payload-interface, fastener-access, and cable-clearance fit tests using the educational fixture.
  20. 20
    DAY 5 — Compare predicted mass, machining time, and dimensions with the physical results.
  21. 21
    DAY 5 — Identify whether the most important improvement belongs in the CAD design, drawing, CAM strategy, setup, machining procedure, inspection plan, or operator workflow.
  22. 22
    DAY 5 — Revise the digital manufacturing package without remachining unless a second production run is approved.
  23. 23
    DAY 6 — Prepare the final design review with the mission, requirements, CAD, drawing, CAM, NC code, setup, physical part, inspection, fit test, nonconformances, revision, and recommendation.
  24. 24
    DAY 6 — Each student completes an individual reflection identifying personal contributions, technical learning, safety decisions, and evidence-based improvements.
  25. 25
    DAY 6 — Archive the final Fusion file, drawing PDF, NC file, setup sheet, production log, inspection report, fit-test report, presentation, and reflection in the manufacturing portfolio.
Required checkpoints

Stop and Verify Before Moving On

Gate 1 — Digital thread approved

Requirements, design, drawing, CAM, simulation, post, and inspection plan match.

Gate 2 — Machine setup approved

Workholding, work zero, tool, controller preview, and dry run pass.

Gate 3 — Part disposition

Inspection and fit-test evidence determine accept, rework, reject, or educational prototype status.

Gate 4 — Final review

Revision and recommendation are supported by manufacturing evidence.

Safety and process control

Required Operating Habits

  • Use only teacher-approved files, tools, stock, speeds, feeds, and procedures.
  • Preserve the last verified working file or code version.
  • Stop immediately for unexpected motion, unusual sound, vibration, loose workholding, tool damage, or an unclear condition.
  • Do not operate the CNC mill without the required certification, permission, and supervision.
  • Record failed trials, defects, and interventions honestly.
