What dimensional inspection should cover

Dimensional inspection should be tied to function, assembly risk and the approved drawing rather than treated as a final-stage formality.

Incoming checks confirm critical material and supplier dimensions. In-process checks help detect tool wear or fixture movement before a full batch is affected. Final checks verify the released control plan and shipment requirements.

For customer programs, inspection records should use consistent part numbers, revision control and measurement methods so results remain traceable across samples and production orders.
