• Operate CNC machines to manufacture parts to tight tolerances and quality standards
• Inspect finished parts using precision measuring instruments (micrometers, calipers, height gauges, dial indicators, CMM, or optical comparators)
• Troubleshoot programs and edit G-code at the control panel, adjusting speeds/feeds to correct dimensional or surface finish issues
• Perform preventative maintenance on CNC equipment (lubrication, fluid levels, filter cleaning, chip removal, and spindle alignments)
• Monitor machine performance and identify mechanical or electrical anomalies, reporting complex repairs to maintenance technicians
• Maintain cutting tools, including wear monitoring, resharpening, and insert replacement

• Knowledge of G-code/M-code programming logic and CAM software applications
• Knowledge of dimensional metrology tools, precision measurement techniques, and quality inspection methodologies
• Skill in operating and maintaining multi-axis CNC machinery (e.g., 3- to 5-axis mills, multi-turret lathes) and production, welding, paint, and material-handling equipment, including forklifts and hand and power tools
• Skill in using CAD/CAM software to import prints or models, build geometry, and generate accurate toolpaths
• Skill in diagnosing machining errors, tool wear, chatter, and programming bugs and making immediate corrections; skill in mechanical maintenance, including fixture adjustments, tool setting, and machine tear-down
• Ability to visualize complex 3D parts and toolpaths from 2D prints or physical templates, and to adapt quickly to new manufacturing technology, including software, cutting tools, and machinery
• Ability to maintain precision and attention to detail to achieve tight tolerances (e.g., ±0.0005 inches), detect quality defects, determine root cause, and take corrective action
• Ability to meet the physical demands of the shop floor, including standing for extended periods, maneuvering heavy parts or fixtures, and safely operating hand tools
• Ability to communicate effectively verbally and in writing
• Ability to establish and maintain effective, courteous working relationships with coworkers and customers
• Ability to remain calm in stressful situations and to take a teamwork approach to the job by cooperating with others, offering to help others when needed, and considering larger organization or team goals rather than individual concerns
