• Non-conformance records
• Corrective actions

I’ve implemented a digital documentation system that allows quick access to quality records and helps identify trends or potential issues before they become problems.

Quality Management System Integration

Our quality control methods are part of a larger quality management system:

1. Standard Operating Procedures (SOPs)

   • Detailed work instructions
   • Inspection procedures
   • Calibration requirements

2. Training Programs

   • Inspector certification
   • Equipment operation
   • Quality awareness

3. Continuous Improvement

   • Regular audits
   • Performance metrics
   • Process optimization

Equipment Calibration and Maintenance

Regular calibration ensures measurement accuracy:

• Annual calibration of CMM machines
• Monthly verification of measuring tools
• Daily checks of basic instruments
• Preventive maintenance schedules

This comprehensive approach to quality control helps us maintain consistent quality in 5083 aluminum machining. By combining advanced measurement technology with proven inspection methods and careful documentation, we can ensure that parts meet specifications consistently.
