Program 3-, 4-, and 5-axis CNC mills and turning centers (Fanuc / Haas) for aerospace brackets, hydraulic manifolds, and tooling fixtures Cut average cycle time 18% across 40+ recurring jobs by optimizing toolpaths, feeds, and fixture strategy in Mastercam Hold ±0.0005 in. tolerances on critical features; scrap rate under 0.8% over the last 12 months Build and maintain a shared tool library and setup sheets used by 12 machinists across two shifts Partner with QA on first-article inspection plans and CMM probing routines for new part numbers

Wrote and proved-out programs for 2-axis lathes and 3-axis mills producing dies, jigs, and short-run production parts Reduced setup time ~25% by standardizing soft-jaw designs and modular fixtures Trained 4 junior operators on G-code edits, tool offsets, and in-process checks Collaborated with engineering on DFM feedback that cut rework on cast-iron housings by ~30%

Ran Haas VF-series mills and ST lathes; performed offsets, tool changes, and first-piece checks to print Logged SPC data and flagged drift before out-of-tolerance parts reached assembly Cross-trained on manual mill/lathe for prototype and repair work

Relevant coursework: CNC Programming, CAD/CAM, Metrology, Manufacturing Processes, GD&T, and Machine Tool Maintenance. Completed capstone fixture-design and multi-axis milling project.
