Casey Rivera

• Set up and operated Haas VF-series mills and ST-series lathes for stainless, aluminum, and tool-steel production runs, consistently holding ±0.0005 in. tolerances. • Programmed and edited G-code, offsets, work coordinates, and probing routines; used Mastercam and Fusion 360 CAM outputs to reduce setup time by 22%. • Read GD&T drawings and process sheets, completed first-piece approvals, and inspected features with CMM, calipers, micrometers, and height gauges. • Partnered with quality and engineering teams to resolve tool-wear and burr issues, cutting repeat nonconformances by 18% over 12 months. • Maintained 5S work centers and followed lockout/tagout, PPE, and safety procedures across a high-mix production floor.

• Operated Haas and Fanuc CNC mills and turning centers across short- and medium-run jobs, meeting daily production targets with zero lost-time incidents. • Set tools, loaded programs, adjusted feeds and speeds, and verified offsets from setup sheets and engineering drawings. • Performed in-process inspection using micrometers, calipers, pin gauges, and optical comparator; documented SPC checks and corrected drift before scrap occurred. • Collaborated with lead machinists to standardize fixtures and tool lists, improving repeat-job changeover consistency and throughput by 15%.

• Completed a structured apprenticeship in CNC milling, manual machining, print interpretation, and shop math while supporting prototype and low-volume die work. • Assisted with machine setup, workholding, tool changes, deburring, and preventive maintenance under senior machinist supervision. • Verified dimensions against shop drawings with calipers, micrometers, and gauges; recorded inspection results and escalated out-of-tolerance conditions. • Earned strong safety and quality evaluations while building proficiency in Fanuc controls, G-code fundamentals, and precision measurement.
