CNC (Computer Numerical Control)

Written By CR PLASMA

CNC, or Computer Numerical Control, refers to the automated control of machining tools and equipment using computer programming. By translating digital design files into precise machine instructions, CNC enables accurate, repeatable, and efficient manufacturing processes across a wide range of industries.

In technical terms, CNC systems interpret CAD (Computer-Aided Design) or CAM (Computer-Aided Manufacturing) data and convert it into numerical codes, usually G-code or M-code, that direct the motion and function of a machine. This can include operations such as cutting, drilling, milling, routing, plasma cutting, laser cutting, and more. CNC machines operate along multiple axes, often with additional rotational or indexing capabilities, allowing for highly complex geometries and tight tolerances. Integration with automation, tool changers, and feedback systems ensures consistent performance, high productivity, and reduced human error.

Modern CNC technology is also closely tied to advancements in digital manufacturing, where machines connect to networks for monitoring, optimisation, and predictive maintenance. This makes CNC not only a method of control but a cornerstone of Industry 4.0 practices.
