# RemnantRack for operators

Find, reserve and check out a suitable piece, then record a verified cut. Separate lessons cover registration, put-away, returns, quarantine and bin checks.

Audience: Operator

## Find and reserve

1. **Find a piece for a job**

   Find a piece for a job.

   The search includes allowances, kerf, trim and buffer. Looking for a piece does not reserve it.

2. **Enter the finished length**

   Enter the finished length.

   The finished part is 300 millimetres. The processing allowance is separate, so the planned blank is 302 millimetres.

3. **Enter the number of blanks**

   Enter the number of blanks.

   Plan two blanks. RemnantRack accounts for the separating cuts and the released loss allowances.

4. **Review candidates and rejected pieces**

   Review candidates and rejected pieces.

   The job needs a guaranteed 621 millimetres. The 1200 millimetre piece fits, while the 500 millimetre piece is explicitly rejected.

5. **Reserve the chosen piece**

   Reserve the chosen piece.

   Reserve the suitable piece for this job. The transaction rechecks availability so another reservation cannot silently take the same piece.

## Check out at the rack

1. **Open the station**

   Open the station.

   Open the paired Training saw. Each real device must be paired by an owner before an operator uses it.

2. **Start your station session**

   Start your station session.

   Start your own session. The site, units and connection state stay visible. This is a simulated scanner on synthetic stock.

3. **Check out at the station**

   Check out at the station.

   Go to the recorded bin and compare the physical piece with the reservation before removing it.

4. **Reject a different offcut**

   Reject a different offcut.

   The shorter piece has the same material but a different identity. It cannot satisfy this reservation.

5. **Scan the reserved piece**

   Scan the reserved piece.

   Scan the correct 1200 millimetre piece and review its recorded condition and length.

6. **Scan the checkout bin**

   Scan the checkout bin.

   The bin scan supplies location evidence. The command checks it again before checkout.

7. **Confirm it matches the job**

   Confirm it matches the job.

   Confirm only after checking the piece and job together.

8. **Record checkout**

   Record checkout.

   The piece is now in use at this station. The operation retains the demand and policy revision that authorised it.

## Record the cut and remainder

1. **Record what was actually cut**

   Record what was actually cut.

   Use the actual blank count, blank length, cuts and losses. The original plan is shown alongside these entries.

2. **Enter a discrepant remainder**

   Enter a discrepant remainder.

   This deliberately incorrect 560 millimetre measurement leaves twenty millimetres unaccounted for.

3. **Review the discrepancy**

   Review the discrepancy.

   The material balance exceeds the uncertainty budget. If this were the real measurement, record the discrepancy and hold the work for review. Never invent a better measurement to pass.

4. **Enter the checked remainder**

   Enter the checked remainder.

   In this corrected training example, a fresh measurement confirms 580 millimetres. Corrections must come from observation, not from the expected arithmetic.

5. **Review the complete balance**

   Review the complete balance.

   604 millimetres of blanks, six of kerf, ten of trim and the 580 millimetre remainder account for the original 1200 millimetres.

6. **Finish the cut**

   Finish the cut.

   The original piece is consumed. The remainder receives a new identity and label and waits for its own put-away confirmation.
