Thoroughly document all manufacturing processes for repeatability and future use.
Perform research and development machining projects as assigned by the Machine Shop Manager.
Help develop new ideas to increase productivity, improve quality, and reduce rejects.
Set up CNC milling machines (multi-axis) and complete first-piece runs, including first-piece inspections.
Operate CNC milling machines for prototype and production runs, performing required in-process inspections.
Use precision inspection equipment to verify every part meets dimensional and quality requirements.
Troubleshoot machining, tooling, and process issues to ensure maximum uptime and part quality.
Support machine operators when questions or problems arise.
Select, specify, and manage cutting tools and holders optimized for aerospace materials.
Maintain tool inventory levels and collaborate with Purchasing to ensure availability and cost control.
Evaluate new tooling technologies, vendors, and strategies to improve performance, reduce cost, and enhance tool life.
Establish and maintain standardized tool libraries and Mastercam toolpath templates to improve consistency and repeatability.
Design and manufacture required fixtures for machining and assembly operations.
Maintain standardized tool management systems and documentation.
Perform routine maintenance on CNC machine tools as needed.
Ensure machining processes enable unattended or lights-out machining whenever possible.
Ensure all machining operations comply with AS9100 and customer-specific aerospace requirements.
Maintain proper documentation, traceability, and revision control.
Collaborate with Quality Assurance to address nonconformances and implement corrective actions.
Follow all company safety requirements when working with cutting tools, fixtures, and CNC machinery.
Keep the Machine Shop Manager informed of issues that could impact quality, productivity, or delivery.
Work closely with machinists, supervisors, engineers, and quality inspectors to resolve technical challenges.
Provide technical support during program prove-outs and machine operator training.
Attend or conduct meetings as required to support planning, improvement, and problem-solving.
Perform any additional duties assigned by the Machine Shop Manager.
