CNC Programmer

Schedule - 4, 10s - Off Fridays

Overview

A 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 Responsibilities

• Develop 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 Qualifications

• Proficiency 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 & Experience

• Associate 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.
