Department: Machining / Production
Reports To: Machine Shop Supervisor / Production Manager
Job Summary
We are seeking a skilled and detail-oriented CNC Lathe Setup and Operator to join our manufacturing team. The ideal candidate will be responsible for the complete setup, operation, and in-process inspection of CNC (Computer Numerical Control) lathes to produce precision parts according to engineering drawings and specifications. This role requires a strong mechanical aptitude, a deep understanding of machining processes, and a commitment to AS 9100 quality and safety.
Key Responsibilities
1. Setup Duties:
-Analyze and interpret engineering blueprints, technical drawings, and geometric dimensioning and tolerancing (GD&T).
-Select, install, and align appropriate cutting tools, tool holders, and work-holding devices (e.g., chucks, collets, fixtures, bar feeders).
-Load correct CNC programs into the machine controller.
-Establish "zero" and reference points by setting work offsets (G54, G55, etc.) and tool offsets using probes, indicators, or manual touch-off methods.
-Perform first-piece (first-article) inspection by running the program and verifying that all dimensions meet specifications.
-Optimize machining processes by adjusting speeds, feeds, and tool paths (with appropriate approval) to improve efficiency and quality.
2. Operator Duties:
-Operate CNC lathes to run production lots, including loading raw material (bar stock, castings, slugs) and unloading finished parts.
-Monitor machine operation, listen for unusual noises, and observe for any malfunctions or tool wear.
-Perform regular in-process quality checks using precision measuring instruments such as calipers, micrometers, bore gauges, height gauges, and optical comparators.
-Make necessary offset adjustments to the machine to maintain dimensional accuracy and part conformity within tight tolerances.
-Change worn or broken cutting tools as needed and update corresponding tool offsets.
-Deburr parts as they come off the machine, if required by the process.
3. Maintenance & Safety:
-Perform routine operator-level machine maintenance, including checking and topping off coolant and lubricants, and clearing chips.
-Maintain a clean, organized, and safe work area in accordance with 5S principles.
-Adhere to all company safety protocols, procedures, and policies, including the proper use of Personal Protective Equipment (PPE).
-Troubleshoot and resolve minor machine alarms or production issues.
4. Documentation:
-Accurately complete all required documentation, including production trackers, inspection logs, and machine downtime reports.
-Communicate effectively with supervisors, programmers, and quality inspectors regarding production status, part quality, or any technical issues.
Qualifications and Skills
Required:
-High school diploma, GED, or equivalent.
-Minimum of 3-5 years of hands-on experience in setting up and operating CNC lathes.
-Proven ability to read and interpret complex engineering blueprints and GD&T symbols.
-Proficient in the use of standard precision measuring instruments.
-Strong understanding of G-code and M-code; ability to perform minor program edits and offset adjustments at the controller.
-Excellent mechanical aptitude and problem-solving skills.
-Strong attention to detail and commitment to producing high-quality work.
-Ability to work independently with minimal supervision.
Preferred:
-Technical certificate or degree in Machine Tool Technology or a related field.
-Experience with Fanuc controllers.
-Experience with multi-axis lathes, including live tooling, sub-spindles, and/or Y-axis.
-Familiarity with 5S lean manufacturing principles.
-Experience with JobBoss.
-Experience in AS 9100 or ISO 9001 environment.
Physical Demands: Must be able to stand for extended periods. Requires manual dexterity, good hand-eye coordination, and the ability to lift and move materials, typically up to 40 lbs.
Work Environment: This position is based in a machine shop environment. The employee will be exposed to moving mechanical parts, metal chips, noise, and cutting fluids (coolant).
