A quality control (QC) department uses a combination of inspection and process monitoring to ensure parts meet specific standards, including dimensional accuracy, surface finish, and material properties. This involves pre-machining checks (like material verification), in-process monitoring (using sensors and real-time checks), and post-machining inspections with calibrated tools such as CMMs. The department also handles quality management systems, calibration, and continuous improvement through data analysis and feedback loops.
Pre-machining and process setup:
- Verifies incoming raw materials to meet specifications for grade, hardness, and composition.
- Reviews and approves the initial program and setup for new parts, often performing a “first article inspection” (FAI).
- Ensures CNC machine calibration and tooling are correct.
