7. Material Integrity:

– Method: Perform tensile and flexural tests to check for any material weaknesses post-cutting.

– Control: Choose the right acrylic grade and maintain optimal cutting parameters.

Quality Control Measures:

– Standard Operating Procedures (SOPs): Develop and follow detailed SOPs for machine setup, operation, and maintenance.

– Operator Training: Ensure operators are well-trained in handling the CNC machine and performing quality checks.

– Preventive Maintenance: Regularly service the CNC machines to prevent deviations in performance.

– Documentation and Traceability: Keep records of all quality tests and machine settings for traceability and continuous improvement.

Implementing these methods and controls helps in achieving high-quality CNC-cut acrylic products, ensuring customer satisfaction and product reliability.
