Quick answer: It can change contact and fit at guides, attachments and packed coils. The finished condition must satisfy the assembly drawing.
Why should a coating be included in dimensional review?
A pre-coating dimension does not establish final clearance. Coating distribution may also vary at edges and bends. Specify which dimensions are inspected after treatment and ensure the coating process is compatible with the spring's functional behavior.
A practical verification method
Measure finished critical dimensions and check motion in the minimum-clearance assembly condition.
| 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 | Measure finished critical dimensions and check motion in the minimum-clearance assembly condition. | 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.
