Quick answer: Track tool identity and condition alongside material lot and finished dimensional or output measurements.

How can tool wear be distinguished from material variation?
An unexplained output trend may coincide with a new material lot rather than wear. Retain the timeline and compare controlled samples. Do not change tooling solely from a batch average without inspecting the actual wear or geometry that could explain the trend.

A practical verification method
Compare measured tool condition, part geometry and output around the observed change point.
| 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 | Compare measured tool condition, part geometry and output around the observed change point. | 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.
