Set up and operate Haas VF-series mills and ST lathes for tight-tolerance aerospace and automotive components, holding ±0.0005 in. on critical features. Perform first-article inspection and in-process checks with CMM reports, calipers, micrometers, and height gauges; document results to AS9100 procedures. Edit Mastercam toolpaths and G-code offsets, troubleshoot tool wear, and cut average setup time 14% through standardized work instructions. Reduced scrap 18% year over year by tightening SPC checks, improving fixture alignment, and coaching a three-person second shift on 5S and safe work practices.

Performed tooling changes, work offsets, and program edits on Okuma and Haas CNC equipment for low-volume automotive components. Completed SPC checks, micrometer and caliper inspections, and visual checks to keep production within print and control-plan requirements. Partnered with senior machinists to improve tool life 12%, maintain clean setups, and safely train new operators on lockout/tagout and 5S.

Supported machinists with material prep, deburring, tool presetting, and safe machine loading while completing a structured shop apprenticeship. Read mechanical drawings and work instructions, learned basic G-code, and maintained accurate travelers for prototype and repair work. Built foundational skills in GD&T, precision measurement, coolant management, and preventive maintenance.

CNC machining, CAD/CAM, blueprint reading, metrology, and industrial safety coursework; completed a Haas mill programming capstone and CNC lab co-op.
