Experience quality controller to monitor the full process.

1. Material Inspection: Ensure raw materials (e.g., cemented carbide, ceramics, ultra-hard materials) meet standards through chemical composition analysis, hardness testing, and metallographic examination.

2. Dimensional Accuracy Control: Use high-precision measuring equipment (e.g., CMM, optical microscopes) to verify geometric dimensions (e.g., diameter, length, angles) against design specifications.

3. Surface Quality Inspection: Evaluate surface finish, coating uniformity, and defects (e.g., cracks, pores) using tools like surface roughness testers and microscopes.

4. Performance Testing: Conduct cutting tests to assess key performance indicators such as wear resistance, heat resistance, and impact resistance, ensuring reliability in real-world applications.

5. Coating Quality Control: Perform adhesion tests, thickness measurements, and composition analysis on coated tools to ensure uniformity, durability, and performance compliance.

6. Process Monitoring: Implement Total Quality Management (TQM) and Statistical Process Control (SPC) to monitor critical process parameters in real-time, minimizing deviations.
