CNC quality control
Inspection evidence designed around critical features.
Quality documentation should answer the risk in the drawing. The method, frequency, report format and traceability scope are agreed before production—not implied after shipment.

Inspection planning
Choose a method that can verify the requirement
Calipers, micrometers, gauges, optical systems and CMMs serve different features. Measurement uncertainty, access and datum simulation should match the tolerance and geometry.
- Critical dimensions identified before production
- Datum setup aligned to drawing intent
- Appropriate bench, optical or coordinate method
- Report format and sampling agreed
Traceable delivery
Connect the part, record and revision
Material certificates, outside-process records, dimensional results, labels and packing instructions should reference the same controlled order and revision where required.
- Part and drawing revision identification
- Material lot and certificate requirements
- Outside-process documentation scope
- Shipment document and label review
Questions buyers ask
Technical answers before the RFQ.
Is a CMM report always required?
No. Use the method that suits the feature and project risk. If a CMM report is required, define the characteristics and format before quotation.
What is needed for a first-article report?
Provide the drawing, characteristic scope, required template or standard, sample quantity and submission expectations.
