o Load and unload parts, materials, fixtures, tooling, and programs as assigned.
o Monitor machine operation to detect abnormal conditions, tool wear, dimensional variation, or machine alarms.
o Perform tool changes, offset adjustments, and basic machine adjustments within level of training and authorization.
o Assist with or independently perform machine setups, including workholding, tooling, offsets, and machine parameters, based on assigned level.
o Support first-piece verification, production start-up, and repeat production runs to ensure parts meet drawing and quality requirements.
- Precision Inspection and Quality Control:
o Inspect machined components using appropriate precision inspection tools, including micrometers, calipers, indicators, bore gauges, thread gauges, and other shop measurement equipment.
o Read and interpret work instructions, engineering drawings, specifications, and inspection requirements appropriate to the assigned level.
o Verify part dimensions, surface finish, and workmanship throughout production and document results as required.
o Identify and communicate out-of-tolerance conditions, nonconforming material, equipment issues, or process concerns.
o Make corrective adjustments or escalate issues to the appropriate lead, programmer, supervisor, or quality representative based on skill level and authorization.
- Maintenance, Safety, and Documentation:
o Perform routine machine care, cleaning, chip removal, fluid checks, and preventative maintenance activities as assigned.
o Maintain accurate production records, labor reporting, inspection documentation, and traceability records as required.
o Follow all safety rules, quality procedures, company policies, and department standards.
o Maintain a clean, organized, and safe work area using established housekeeping and 5S practices.
- Support and Collaboration:
o Work with operators, leads, programmers, maintenance, engineering, and quality personnel to support safe and efficient production.
o Communicate machine status, production issues, quality concerns, and shift turnover information clearly and accurately.
o Support training, cross-training, troubleshooting, and continuous improvement activities as appropriate to assigned level.
Requirements:
Skills and Qualifications
- Experience, training, or demonstrated aptitude in CNC machining, turning operations, manufacturing, mechanical work, or related technical fields.
- Ability to safely operate CNC turning equipment and follow written and verbal work instructions.
- Ability to read and interpret drawings, specifications, travelers, inspection plans, and manufacturing documentation at a level appropriate to the position.
- Ability to use precision measuring instruments and understand basic inspection practices.
- Working knowledge of machine offsets, tooling, feeds and speeds, G and M codes, and CNC controls, with depth of knowledge increasing by level.
- Strong attention to detail, reliability, communication skills, and commitment to producing quality work.
- Ability to work independently or with supervision depending on assigned level, task complexity, and training status.
Level Guidelines
- Level 1: Entry-level or developing operator who performs basic machine operation, part loading and unloading, routine inspection, documentation, and housekeeping under supervision or with established work instructions.
- Level 2: Intermediate operator who performs routine operation and setup support, makes basic offsets and tool changes, verifies parts, troubleshoots common issues, and works with limited supervision on repeat production.
- Level 3: Advanced operator who performs complex setups, supports first-piece or first-article verification, troubleshoots machine and process issues, supports process improvements, and may assist in training or mentoring lower-level operators.
Preferred Qualifications
- Experience operating CNC turning centers, screw machines, Swiss-style machines, or multi-axis turning equipment.
- Experience machining tight-tolerance components in aerospace, defense, medical, or other precision manufacturing environments.
- Familiarity with GD&T, CNC program verification, setup documentation, lean manufacturing, and continuous improvement practices.
Additional Hiring Requirement
- Candidates may be required to complete a technical machining assessment, practical machine evaluation, blueprint reading exercise, or precision measurement assessment appropriate to the level being considered.
