What Is Quality Assurance in CNC Machining?

Quality assurance in CNC machining is the process of verifying that every machined part meets drawing specifications before it ships. It includes dimensional inspection using a CMM (coordinate measuring machine), GD&T verification, material certification, and documentation that proves your parts are correct. At RivCut, QA is not an add-on — it is built into every order.
1

Machine to Spec

Parts are CNC machined to your drawing tolerances using calibrated equipment and verified toolpaths.

2

CMM Inspect

Every critical dimension is measured on our CMM. Actual values are compared to nominal specs.

3

Document & Ship

Inspection reports, material certs, and conformance documents ship with your parts.

Why RivCut

Built-In Quality on Every Order

Most shops charge extra for inspection. We include it as standard — because shipping uninspected parts is not an option.

CMM on Every Order

Every order gets CMM inspection before shipping. We measure critical dimensions and compare actual values to your drawing tolerances. No exceptions, no extra charge.

NIST-Traceable Equipment

Our CMM and gauges are calibrated to NIST-traceable standards. Measurement accuracy to ±0.0001". Your quality team can trust the numbers.

Full Documentation

Dimensional inspection reports, material certs with heat lot traceability, first article reports, and certificates of conformance. Everything ships with your parts.

Industry-Specific Compliance

We support aerospace, defense, medical, and automotive documentation requirements. AS9100-style records, FAI reports, and MIL-STD-ready paperwork available.

What We Inspect

Quality Assurance Services

From first article inspection to surface roughness testing — every measurement documented and traceable.

CMM Inspection

Full 3D coordinate measurement of critical dimensions, hole positions, angles, and geometric features. Every measurement compared to your drawing tolerances.

±0.0001" accuracy

First Article Inspection (FAI)

Complete measurement of the first part from every production run. Detailed report with actual vs. nominal values for every ballooned dimension. You approve before we continue.

Full balloon report

GD&T Verification

Flatness, parallelism, perpendicularity, position, runout, concentricity, and true position. If your drawing calls it out, we measure and report it. See our GD&T reference guide for symbol definitions.

All GD&T callouts

Material Certifications

Every metal order ships with a mill cert proving alloy, heat lot, and chemical composition. Full traceability from raw stock to finished part.

Heat lot traceability

Surface Roughness Testing

Profilometer measurement of surface finish (Ra values). Verify mating surfaces, sealing faces, and cosmetic requirements meet your spec.

Ra measurement

Certificate of Conformance

Formal documentation stating that parts conform to purchase order specifications. Supports receiving inspection and quality system requirements.

FAQ

Questions About Quality Assurance

A CMM measures dimensions, positions, angles, and geometric tolerances on your part. It checks features like hole locations, flatness, parallelism, and more. Every measurement is compared to your drawing.
Yes. We measure the first part from every production run completely. You get a detailed report with actual vs. nominal values for every dimension. You approve it before we continue production.
Yes. We measure GD&T callouts including flatness, parallelism, perpendicularity, position, runout, and concentricity. If your drawing calls it out, we can measure it.
