CNC Programmer

CNC ProgrammerA CNC Programmer converts engineering designs into machine-ready G-code and machining strategies. They work closely with machinists, engineers, and quality teams to ensure efficient, accurate, and safe production.Core Duties and ResponsibilitiesDevelop CNC toolpaths from 2D/3D models using CAM software (Mastercam, NX CAM, Fusion 360, Hypermill).Write, edit, and optimize G/M-code for mills, lathes, and 3/4/5-axis machining centers.Select cutting tools, holders, speeds, feeds, and machining strategies based on material and tolerance requirements.Read and interpret blueprints, GD&T, and engineering specifications.Post-process CAM outputs for specific machine controllers (Fanuc, Siemens, Heidenhain).Conduct simulations, dry runs, and first-article prove-outs to verify program accuracy.Adjust programs and processes to improve cycle time, tool life, and part quality.Perform machine setups, monitor operations, and troubleshoot defects or malfunctions.Maintain documentation such as setup sheets, tooling lists, and machining sequences.Required Skills and QualificationsProficiency with CAM software (Mastercam, Fusion 360, GibbsCAM, Edgecam).Strong understanding of machining principles, GD&T, and material behavior.Ability to read blueprints, engineering drawings, and technical specifications.Familiarity with CNC controllers (Fanuc, Siemens, Heidenhain).Experience with machine setup, tooling selection, and inspection tools.Problem-solving skills and ability to optimize machining processes.Typical Education & ExperienceAssociate degree in machining/manufacturing technology or vocational certificate.3–8 years of machining or CNC programming experience.Certifications: Mastercam Certification, Autodesk Fusion 360 Machining Certification, NIMS CNC Programming.
