Quick answer: Specify tight limits only where function requires them, while preserving enough information to define the useful curve.
Does every point need a narrow tolerance?
An unnecessarily dense set of narrow targets can impose manufacturing burden without improving performance. Conversely, sparse endpoints may omit critical behavior. Explain the functional importance of each point so design and inspection focus on the actual need.
A practical verification method
Compare the proposed acceptance points with system behavior and identify which positions determine pass or fail.
| 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 the proposed acceptance points with system behavior and identify which positions determine pass or fail. | 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.
