CNCprogrammering

CNCprogrammering refers to the discipline of creating numerical control programs that drive CNC machines to manufacture parts. In Danish usage, the term designates the activity of programming and preparing instruction sets for computer-controlled manufacturing equipment. Programs are typically written in G-code or generated by CAM software and then post-processed to match a specific machine control.

A CNC programmer works with milling, turning, drilling, or multi-axis machines. The programmer designs toolpaths, selects cutting tools, and sets feeds and speeds, passes, tolerances, and quality checks. They also account for machine kinematics, fixtures, workholding, and the limitations of the equipment.

The workflow usually starts with a CAD model, which is translated in CAM to an NC program. The code is verified by simulation, refined to optimize efficiency and accuracy, and finally post-processed to the machine’s control dialect. On the shop floor, the program is loaded, tested with light cuts, and adjusted as needed to achieve the required results.

Skills and tools include proficiency in G-code or ISO programming, familiarity with CAM software (such as Fusion 360, Mastercam, or Edgecam), and a solid understanding of coordinate systems, datum references, and measurement methods. Knowledge of materials, tooling, speeds and feeds, cutting strategies, and safety practices is essential for reliable production and documentation.

CNC programmers are employed across manufacturing sectors such as aerospace, automotive, medical devices, and consumer electronics. Typical environments include job shops and production facilities. Education often comes from technical schools, apprenticeships, or on-the-job training, with ongoing learning as controls and software evolve. The role aims to optimize cycle times, improve part accuracy, and enable consistent, repeatable production.
