CNC Setup Programmer / Operator

Dunbarton Corporation is seeking a CNC Setup Programmer / Operator to join our Camden Tennessee team who is responsible for the fabrication, finishing, and movement of Dunbarton products at the Camden Plant.

Essential Job Functions

• Interpret engineering prints, blueprints, drawings, and templates to determine dimensions, tolerances, and process specifications
• Convert design specifications into CNC machine code using CAD/CAM software (e.g., Mastercam, SolidWorks) or manual G-code programming
• Calculate feeds, speeds, tool paths, and depth of cuts for optimal machining efficiency and part accuracy
• Set up CNC machinery, including installing work-holding fixtures, jaws, chucks, collets, and cutting tools
• Load program instructions into machine controls, set tool offsets, work offsets, and zero reference points
• Perform first-piece inspection and dry runs to verify program accuracy and clearance safety before full production
• 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
• Maintains a safe, orderly work area; wears assigned PPE; follows Lock-Out/Tag-Out procedures; and follows safety, 6S, LEAN, and Kaizen programs
• Remains cross-trained on all plant work stations; trains and mentors other employees; attends required training and meetings
• Adheres to work schedule and attendance requirements, including regular on-site attendance at Dunbarton facilities and nights and weekends as required; regular on-site presence is an essential function of this position
• Performs other work as directed and required

Knowledge, Skills, and Abilities

• Knowledge of metalworking and fabrication processes, cutting tool geometry, material properties, and heat treatment principles
• Knowledge of 2D/3D engineering print reading, welding symbols, and Geometric Dimensioning and Tolerancing (GD&T) principles per ASME standards
• 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
