Quick answer: Link the approved drawing revision to purchasing, work instructions, tooling setup and inspection records.
How can an obsolete drawing be kept out of production?
A revised file in one folder does not prove the shop uses it. Confirm the route for replacing controlled copies and identifying parts already made. State the effective batch or date and any disposition for older stock.
A practical verification method
Trace a current work order through its drawing, setup and inspection documents to confirm consistent revision.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Trace a current work order through its drawing, setup and inspection documents to confirm consistent revision. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
