First-piece inspection checks whether the released instructions and setup produce the required result before the full run proceeds.

First-piece inspection checks whether the released instructions and setup produce the required result before the full run proceeds. Choose checks from the drawing, hardware requirements, and agreed acceptance criteria. Do not rely on appearance alone when fit depends on machining details.

## Define the release check

- Confirm job, part identity, and drawing revision.
- Check the dimensions and machining features critical to the next operation.
- Verify orientation, handedness, edge treatment, and material specification.
- Record acceptance or the corrective action before continuing the batch.

## A small-batch example

For a hypothetical run of 40 matching doors, inspect the first completed part before repeating a drilling pattern. Discovering an orientation error after one part creates a different recovery problem than discovering it after all 40.

## Keep the evidence useful

Record which requirement was checked and who released the run. A generic approved box does not explain the decision if the next station later finds a problem.

## How Millbase can help your shop

### Keep the shop’s operational picture connected

For a cabinet or millwork project, [Millbase project tracking](https://millbase.ca/#projects) connects the job, sub-projects, tags, recorded labour, and material costs. Pair that context with [inventory records](https://millbase.ca/#inventory) when reviewing the materials used and the work still being discussed. Keep the approved drawings and manufacturer requirements available through the shop’s established document process.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Show the recorded labour and material costs for this cabinet project, and who has worked on it.”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Use the answer to prepare a focused review of the job. It does not establish hardware compatibility, approve a drawing revision, or replace a manufacturer’s instructions or the contract specification.

## Frequently asked questions

### Does first-piece approval replace later checks?

No. Process changes, tool wear, material variation, or interruptions may justify additional verification under the shop's quality plan.

### Who should approve the first piece?

Assign someone competent to evaluate the relevant requirements, with authority to stop and correct the run.
