This role is for individuals passionate about precision engineering, problem-solving, and working with advanced technology. It offers the satisfaction of translating complex designs into tangible, high-quality components and optimizing manufacturing processes. However, it demands meticulous attention to detail, strong analytical skills, and continuous learning to keep up with evolving software and machinery.”
About This Role
Develops precise instructions for computer-controlled machines to create complex metal and plastic components.
A Day in the Life
A CNC/CAM Programmer spends their day translating engineering designs into precise instructions (G-code) for Computer Numerical Control (CNC) machines. This involves using CAM software to create toolpaths, simulating machining operations, optimizing programs for efficiency and quality, and troubleshooting issues on the shop floor.
- Interpret engineering drawings, blueprints, and 3D models to understand part specifications
- Select appropriate tools, cutting speeds, and feed rates for machining operations
- Use CAM (Computer-Aided Manufacturing) software to generate efficient toolpaths
- Write and edit G-code and M-code programs for CNC milling, turning, and grinding machines
- Simulate machining processes to detect potential collisions or errors before actual production
- Optimize CNC programs for reduced cycle times, improved surface finish, and tool life
- Collaborate with machinists and engineers to troubleshoot programming and machining issues
- Perform first-article inspections to verify part accuracy and quality
Work Environment
Works in an office setting for programming, but also spends significant time on the factory floor, interacting with CNC machines and machinists. The factory environment can be noisy and may involve exposure to coolants and metal dust.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Generally good work-life balance, but urgent production runs, complex part development, or machine breakdowns can sometimes require extended hours.
