Responsibilities

Program Development: Utilize software such as Mastercam, CATIA, or Siemens NX to create toolpaths for 3-, 4-, and 5-axis milling and mill-turn machines. Designing complete NC programs for complex 3, 4, and 5-axis mills, lathes, and mill-turns using CATIA V5/V6

CAD/CAM Integration: Analyze 3D CAD models and blueprints to determine the most efficient machining sequences and work-holding strategies

Tooling & Fixture Design: Design custom fixtures and jigs in CAD to secure aerospace components during the machining process

Simulation & Verification: Conducting machine simulations (e.g., using Veri cut or Completed) to ensure error-free toolpaths before physical production

Process Optimization: Continuously refine programs to reduce cycle times, improve tool life, and ensure consistent quality for high-value aerospace parts like landing gear or turbine blades. Researching tools and methods to reduce cycle times, improve part quality, and ensure cost-effective manufacturing

Documentation: Create detailed setup sheets and tool lists to guide machinists through the production process

Shop Floor Support: Troubleshooting programming issues during setup, performing "prove-outs" on the floor, and mentoring machine operators
