2. Surface Roughness Testing:

– Advantages: Assures smooth surface finishes, critical for part functionality.

– Control: Employ surface roughness testers (profilometers) to measure and ensure surfaces meet required roughness parameters.

3. Material Hardness Testing:

– Advantages: Verifies that materials maintain their hardness post-machining.

– Control: Utilize Rockwell or Vickers hardness testers to measure material hardness and ensure consistency.

4. Non-Destructive Testing (NDT):

– Advantages: Identifies internal defects without damaging parts, ensuring integrity.

– Control: Apply methods like ultrasonic testing, X-ray, and dye penetrant testing to detect internal flaws.

5. Geometric Accuracy Testing:

– Advantages: Ensures the overall geometric integrity of the part.

– Control: Use laser interferometry and ball bar testing to check machine calibration and part geometry.

6. Functional Testing:

– Advantages: Confirms that parts perform their intended function.

– Control: Conduct assembly and operational tests to ensure parts fit and function as required.

Quality Control Practices:

– Calibration: Regularly calibrate measuring instruments and CNC machines to maintain accuracy.

– Documentation: Maintain detailed records of inspections and test results for traceability.

– Process Control: Implement Statistical Process Control (SPC) to monitor and control the machining process.

– Training: Ensure operators and inspectors are well-trained in quality standards and testing procedures.

– Preventive Maintenance: Regular maintenance of CNC machines to prevent defects due to equipment wear.

These methods and controls ensure high-quality output, minimize errors, and maintain the integrity of CNC machined parts.
