– Calipers and Micrometers: For precise measurement of dimensions.

2. Material Testing:

– Tensile Testing: Determines the material’s strength and ductility.

– Hardness Testing: Measures the resistance of steel to deformation (e.g., Rockwell, Brinell tests).

– Chemical Analysis: Ensures the steel composition meets the required standards (e.g., spectroscopy).

3. Surface Finish Inspection:

– Surface Roughness Testers: Assess the smoothness of the machined surface.

4. Non-Destructive Testing (NDT):

– Ultrasonic Testing: Detects internal flaws and measures thickness.

– Magnetic Particle Inspection (MPI): Identifies surface and near-surface defects.

– Radiographic Testing (X-ray): Reveals internal defects.

5. Visual Inspection:

– Microscopic Examination: For identifying surface irregularities and defects.

Quality Control Measures

1. Standard Operating Procedures (SOPs): Ensure consistent process adherence.

2. Process Control:

– Statistical Process Control (SPC): Monitors the production process through statistical methods.

– Control Charts: Track process variations over time.

3. Calibration:

– Regular calibration of tools and machines to maintain measurement accuracy.

4. Documentation:

– Detailed records of inspections and tests to trace issues back to their source.

5. Training and Certification:

– Ensuring operators and inspectors are well-trained and certified.

By employing these testing methods and quality control measures, manufacturers can ensure the high quality of steel CNC machined parts, meeting both customer specifications and industry standards.
