Session 13: Cut & Evaluate Your Practice Build

Session 13

Cut Your Practice Build

Real Material Today

Four weeks of design, materials, safety, and CAM — all of it, running on the actual machine.

Before Anything: Your Checklist

Walk your Session 10 pre-cut checklist one more time, against this exact job, before touching the machine.

Every Session 4 Protocol Still Applies

Certified, supervised, one job at a time — nothing about today changes those rules.

Today's Sequence

  1. Confirm material is secured
  2. Verify zero/home
  3. Run the job, supervised, start to finish
  4. Remove tabs by hand once cutting is done

If Something Goes Wrong

Stop the job. Diagnose using Session 10's symptom list before assuming anything.

A Failed First Attempt Isn't a Failed Session

Diagnosing a real problem, correctly, is worth as much as a clean first cut — same philosophy as Unit 1's Mismatch Activity.

Two Things to Remember

Watch the whole cut.

Never leave a running job unattended — Session 4's rule, still true, no exceptions today.

Two Things to Remember

Keep the part, even if it's imperfect.

Next session is about evaluating what actually happened — you need the real result, not just a memory of it.

Then: Bring Back the Calipers

While other teams are on the machine, you are not waiting — you are evaluating. Same tool as Unit 1 Session 6, same discipline, real stakes this time.

Measure what actually matters: outer dimensions, pocket depth, hole location.

A Mismatch Isn't a Failed Session

A part that came out 2 mm undersized with a correct diagnosis is worth more than a part that happened to come out right for reasons nobody can name.

Four Weeks, One Thread

Client communication → materials → CAD → CAM → safety. Every one of them shows up in the part in your hand.

Next Up

The real brief arrives.

Same five skills, a real client, and a cabinet that has to work.

Step 1: Final Checklist Pass

Walk your Session 10 pre-cut checklist one more time against your actual Session 12 job file.

Step 2: Load, Secure, Zero

Load your stock, confirm it's fully secured, and verify your zero point — per Session 4's protocols.

Step 3: Run the Job, Supervised

Run the job start to finish. Stay with the machine the entire time.

Step 4: Remove Tabs and Inspect

Once the job finishes, remove any tabs by hand and take a first look at your part. Check for tear-out, tab marks not fully cleaned up, or any surface roughness, and note anything you find.

Step 5: Measure Your Part

Calipers, real readings, not estimates. Do this at your bench while other teams are on the machine.

Step 6: Diagnose Any Mismatch

For any dimension that differs from your design by more than a small amount, use Sessions 7–10's concepts to explain why — offset, step-down, material behavior, or something else.

Step 7: Unit Recap

List the five main skills from this 4-week arc: client communication, materials (subtractive and additive), CAD, CAM, and safety certification. For each, write one sentence on how it showed up in your practice build specifically.

Checkpoint

Before you leave the machine, confirm:

  • You stayed with the job for its entire run
  • You have the physical part in hand, whatever its condition
  • If anything went wrong, you have a first-guess diagnosis written down, not just "it didn't work"
  • Real measured dimensions in your table, not estimates
  • A specific diagnosis for any mismatch — not "it just came out wrong"
  • All five Manufacturing Foundations skills named in your recap

Reflection

Answer these on your own. Reflections are individual, even when the rest of the session was team work.

  1. Did anything go wrong during the cut? If so, give your first-guess diagnosis using Session 10's symptom list. If nothing went wrong, name the symptom you were most watching for.
  2. Of the five Manufacturing Foundations skills, which one do you feel least confident applying to a real, higher-stakes project starting next week?
  3. This is the last session before a real client brief arrives. What's one thing about your own process you want to do differently once the stakes are real?
