• Install and adjust cutting tools appropriate to the material, part geometry, and operation.
• Apply approved manufacturing methods, setup documentation, tooling standards, and production procedures.
• Determine and adjust feeds, speeds, and depth of cut to achieve required dimensions, surface finish, and tool life.
• Deburr and finish precision-machined parts according to engineering drawings and route sheets, maintaining required edge breaks and chamfers.
• Inspect in-process and completed parts using appropriate measurement equipment, including calipers, micrometers, gauges, and comparators; document results as required.
• Perform routine machine care and housekeeping to support equipment cleanliness, accuracy, and reliability; report equipment issues promptly.
• Identify opportunities to improve safety, quality, cycle time, and workflow; recommend and support process improvements and lean initiatives.
• Follow company policies and procedures, including safety requirements, and maintain a clean and orderly work area.
• Review CAD files and use Mastercam to interpret geometry and extract dimensions needed for programming and machining.
• Ensure finished parts are burr-free and free of machining or handling defects, including chatter, gouges, scratches, poor surface finish, embedded chips, and missing edge breaks or chamfers.
• Verify completed setups and parts against the applicable drawings, specifications, and work instructions.
• Perform other job-related duties as assigned

Qualifications & Skills:

• High school diploma or equivalent.
• At least 3 years of hands-on machining experience.
• At least 1 year of CNC programming experience.
