Machine operator resumes that say 'operated production equipment' tell hiring managers nothing useful. Name every machine type, brand, and material you've worked with: '3-axis Haas CNC mills machining 6061 aluminum and 4140 steel.' This specificity lets supervisors immediately assess your fit for their production environment.

First-pass yield, scrap rates, defect parts per million (DPPM), and inspection pass rates are the quality metrics that matter in manufacturing. Include yours alongside the production volume context: '98.5% first-pass yield at 1,500 parts/week.' This combination of quality and throughput is exactly what quality-conscious manufacturers want to see.

Operators who can perform their own setups and changeovers are more valuable than those who require a setup technician. Document your average changeover time, the number of unique part numbers or fixtures you've set up, and any SMED or lean manufacturing training you've completed. Setup capability directly reduces production costs.
