Job Summary

A CNC Process Engineer is responsible for developing, optimizing, and troubleshooting CNC machining processes to ensure efficiency, precision, and high-quality production output. They bridge the gap between design and manufacturing, focusing on tooling, programming, and process improvements.

Key Responsibilities

• Process Development & Optimization
  • Design, implement, and refine CNC machining processes.
  • Select cutting tools, speeds, feeds, and parameters for optimal performance.
  • Reduce cycle times, scrap, and rework through continuous improvement.
• Programming & Tooling
  • Create and modify CNC programs using CAD/CAM software, G Code.
  • Develop detailed process plans and work instructions for operators.
  • Ensure proper tooling design and setup for precision machining.
• Quality & Compliance
  • Collaborate with Quality Control for first-piece inspections.
  • Apply statistical process control (SPC) and root cause analysis for defects.
  • Maintain compliance with industry standards and safety regulations.
• Troubleshooting & Support
  • Diagnose machining issues and implement corrective actions.
  • Provide technical support to production teams and operators.
  • Train staff on CNC processes and best practices.
• Process documentation and standardization
  • Create and maintain process documentation including work instructions and PFMEA.
  • Support implementation of lean manufacturing principles.
  • Collect and analyze data to implement improvements (cycle time, efficiency).

Skills & Qualifications

• Technical Expertise
  • Strong knowledge of CNC programming, machining techniques, and CAD/CAM tools.
  • Familiarity with GD&T (Geometric Dimensioning & Tolerancing).
  • Fixture design and work supports.
  • Understanding of materials science (metals, composites, plastics).
  • Experience in GROB and/or SW Equipment.
• Problem-Solving
