Computer Numerical Control (CNC) Programming

Computer Numerical Control (CNC) Programming is the process of creating a set of instructions, typically in a language called G-code, to direct the automated movements of a machine tool like a mill or lathe. These instructions govern every aspect of the manufacturing operation, dictating the tool's path, cutting speed, feed rate, and the use of auxiliary functions such as coolant. The ultimate goal of CNC programming is to translate a digital design, often originating from a Computer-Aided Design (CAD) model, into a precisely machined physical part. This code can be written manually or, more commonly, generated automatically by Computer-Aided Manufacturing (CAM) software, enabling the production of complex components with high accuracy and repeatability.
