• Monitor production runs and adjust tooling, offsets, or processes as needed.
• Set up and operate CNC vertical machining centers and horizontal lathes.
• Perform MDI (Manual Data Input) programming.
• Monitor part quality throughout the machining process.
• Participate in Lean Manufacturing and continuous improvement initiatives.

Quality & Inspection

• Read and interpret blueprints, engineering drawings, and GD&T requirements.
• Inspect first-piece and in-process parts using micrometers, calipers, indicators, and other precision measuring equipment.
• Maintain tight tolerances and proactively address quality concerns.

Process Improvement & Troubleshooting

• Work with programmers and engineers to improve setup efficiency, cycle times, and repeatability.
• Follow setup sheets, tooling lists, and work instructions.
• Troubleshoot machining issues related to tooling, fixturing, materials, and machine performance.
• Support process standardization, scrap reduction, and production efficiency efforts.

Required Qualifications
