Quality Control Workflow from Incoming Material to Final Inspection

1

Step 1: IQC (Incoming Quality Control):

Incoming material and purchased components are reviewed against project requirements, material documents and inspection criteria before production starts.
2

Step 2: FAI (First Article Inspection):

For new or repeat production programs, first article inspection can be used to confirm key dimensions, inspection points and the approved production baseline.
3

Step 3: IPQC (In-Process Quality Control):

During production, critical dimensions and process conditions can be checked according to the inspection plan to reduce batch variation and detect issues early.
4

Step 4: OQC/FQC (Final Quality & Outgoing)

Final inspection and outgoing quality checks help confirm dimensional results, documentation status, packaging requirements and traceability records before shipment.

Automated Optical Inspection (AOI) for Batch Verification

For high-volume components and complex geometries, AOI can help verify dimensions, edge conditions and surface features efficiently. The inspection method and sampling level should be defined according to project requirements.

CNC Machining Quality Control FAQ

Common questions about inspection documentation, FAI, CMM reports and traceability before starting a CNC machining project.

Depending on project requirements, quality documentation may include dimensional inspection records, FAI reports, CMM reports, material-related documents and compliance-related records. The exact document package should be confirmed during RFQ or quality review.

First article inspection can be used for new parts, repeat production programs or design changes. It helps confirm key dimensions, inspection points and the approved production baseline before moving into larger production quantities.

CMM reports can be provided based on project requirements, part geometry and inspection plan. During RFQ review, our team can confirm which dimensions should be measured by CMM and what report format is needed.

Material batch information, production records and inspection results can be linked to manufacturing lots when required by the project. This helps purchasing and quality teams review repeat orders, investigate deviations and maintain stable supplier performance.

No. The inspection plan should be defined according to part function, material, tolerance requirements, critical dimensions, production volume and customer requirements. High-risk or repeat production parts may require more detailed documentation.

Yes. Customers can upload drawings and quality requirements before quotation. Our team can review key dimensions, inspection documentation needs, FAI, CMM report requirements and traceability expectations before confirming the quality plan.
