Ensuring parts meet drawing requirements is a core function of our quality control process, which integrates checks at every stage of production. The process begins with a thorough drawing review and programming validation to prevent errors before machining starts. During the CNC machining run, we conduct a “first-off inspection” to verify that the initial part is dimensionally perfect. This is followed by regular in-process inspections at critical steps to monitor consistency and maintain dimensional accuracy.

Upon completion, every part undergoes a rigorous final inspection. For components with simple geometries, we use calibrated precision instruments like digital calipers, micrometers, and height gauges. For parts with complex features and tight tolerances, we utilize a Coordinate Measuring Machine (CMM). This advanced CMM inspection provides a detailed report comparing hundreds or thousands of measured points against the original CAD model, offering the highest level of verification and guaranteeing that the final product strictly adheres to all drawing specifications.

Key Strengths and Considerations of This Process

Strengths:

• Prevents production of non-conforming parts, saving time and materials.
• Provides documented proof of quality and full traceability for every part.
• Enables the reliable manufacturing of highly complex and critical components.

Considerations:

• Rigorous inspection adds a necessary time component to the overall lead time.
• The cost of advanced metrology equipment can influence the final part price.

How We Do It Our workflow mandates a first-article inspection for every setup, followed by scheduled in-process checks by our operators. Finally, our dedicated quality assurance team conducts a 100% final inspection, using CMMs and other calibrated tools to generate a comprehensive report for every batch.

Expected Outcome This multi-layered approach guarantees that you receive parts that are dimensionally correct, fully compliant with your drawings, and ready for immediate integration into your assembly.
