Job Title: Mastercam/MazaCAM Mill Operator
Department: Machine Shop
FLSA Status: Hourly $27-$35 per hour
SUMMARY:
The Mastercam/MazaCAM Mill Operator is responsible for programming, setting up, and operating CNC milling machines using Mastercam to produce high-quality components to print. This role ensures parts meet all dimensional, quality, and delivery requirements while maintaining a safe and organized work environment.
Key responsibilities
- Create and edit 2D/3D toolpaths in Mastercam/MazaCAM from customer or internal CAD models and drawings.
- Set up CNC mills, including work holding, tooling selection, tool offsets, work offsets, and program loading.
- Read and interpret engineering drawings, blueprints, and GD&T to determine machining strategies and critical features.
- Run first-article parts, verify dimensions using appropriate measuring tools, and adjust programs/offsets to hold tolerances.
- Optimize feeds, speeds, and toolpaths to improve cycle time, tool life, and surface finish while protecting equipment.
- Perform routine machine maintenance, keep work area clean, and follow all safety procedures and PPE requirements.
- Document setups, programs, and process notes to support repeatability and standard work.
- Collaborate with engineers, quality, and supervisors to resolve machining issues and continuously improve processes.
Required qualifications
- Previous experience programming and operating CNC mills using Mastercam/MazaCAM in a production or job-shop environment.
- Strong ability to read blueprints, CAD models, and apply GD&T; comfortable working with tight tolerances.
- Proficiency with precision measuring tools such as calipers, micrometers, height gauges, and indicators.
- Solid understanding of CNC G-code, cutting tools, work holding, and machining best practices.
- Demonstrated commitment to safety, quality, and meeting production schedules on first shift.
- High school diploma or equivalent; additional technical training in machining or CNC programming preferred.
Preferred skills
- Experience machining steels, stainless, alloys, or similar industrial materials.
- Familiarity with multi-axis milling, probing cycles, and advanced Mastercam/MazaCAM features.
- Basic knowledge of lean/5S practices and continuous improvement in a machining environment.
- Ability to train others on setups, safe operation, and basic Mastercam/MazaCAM workflows.
