Job Summary
Responsible for performing precision setups and operations on multi-axis CNC milling and turning machines. In this role, you will prepare machines for production by installing tooling, fixtures, and programs, validating first-article parts, and ensuring parts meet strict quality and dimensional standards.
Essential Duties and Responsibilities
The duties and responsibilities described are not a comprehensive list and additional tasks may be assigned. To perform this job successfully an individual must be able to perform each essential duty satisfactorily.
Automation & Continuous Improvement
- Collaborate with Programming and Manufacturing Engineers to optimize machining processes suitable for automation (robotic loading, in-process inspection & probing) to support lights-out manufacturing.
- Apply continuous improvement principles to machining processes to improve efficiency, reduce lead times, and eliminate non-value-added activities.
Quality & Problem Solving
- Diagnose machining issues, perform root-cause analysis, and implement sustainable corrective actions.
- Ensure adherence to tight tolerances using advanced inspection tools and techniques.
- Read and interpret GD&T, engineering drawings, and 3D part models to ensure precision manufacturing.
Training & Leadership
- Develop and maintain detailed setup documentation, including setup sheets, tooling files, and manufacturing inspection plans.
- Mentor and train less experienced machinists in setup techniques and process control.
- Promote a culture of craftsmanship, accountability, and continuous improvement.
Qualifications, Experience and Education Requirements
- High School diploma or equivalent
- 5+ years hands-on experience in CNC precision machining (aerospace, defense, or medical).
- Expertise in G-code, canned cycles, and in-process probing systems.
- Proven track record of machining tight-tolerance parts using aluminum, steel, and aerospace-grade alloys.
- Understanding of metal behavior & mechanics in a machining environment (chip formation, vibration, distortion, heat transfer, etc.)
- Understanding of cutting tool geometry, fixture design, and tool life management.
- Ability to interpret GD&T and manufacturing drawings.
- Proven ability to diagnose and resolve complex machining issues independently — from chatter and tool wear to dimensional instability and setup inefficiencies.
- Experience with standard MS Office tools (Excel, Outlook)
