Spring In-Process Inspection at Functional Features

Quick answer: Prioritize features whose later correction is difficult or whose variation changes retention, travel or output.

Which features deserve checks before final assembly?

Inspection at every step is not inherently useful. Select checks based on the failure path and manufacturing route. Define what happens when a result is outside limits so defects are contained before more work is added.

A practical verification method

Follow a sample through the route and verify that the chosen checks detect the identified failure conditions.

ItemWhat to recordPurpose
Reference configurationPart or assembly identity and drawing revisionMake comparisons traceable
Test conditionsRelevant position, direction and operating conditionCompare the same characteristic

Verification plan for spring in process functional inspection: recommended check, retained evidence and decision boundary
Original verification plan for this specific decision. Acceptance values must be agreed for the actual product.

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.
