BHow a part is inspected

Checked at every gate.

Inspection is planned with the process, not bolted on at the end. Every characteristic on your drawing is ballooned and accounted for.

First-off
Full dimensional check before the batch runs, signed by the setter and an inspector.
In-process
Machine probing on critical features, operator checks at a defined frequency, results logged to the job.
First article
AS9102 FAIR for aerospace, with ballooned drawing and characteristic accountability.
SPC
Control charts on key characteristics; Cpk reported to customers monthly.
Final
CMM, optical or manual inspection to the inspection plan, visual check to your cosmetic standard.
Release
Certificate of conformity, material certificates and reports packed with every delivery.
Non-conformance
Quarantined, recorded, root-caused using 8D, never shipped on concession without your written approval.
CMetrology equipment

The lab. Calibrated, traceable, temperature-controlled.
