CNC machining, or Computer Numerical Control machining, is a manufacturing process that utilizes computerized controls and precise machine tools to automate the production of complex components from raw materials. It involves the use of computer-programmed instructions to control the movement of cutting tools, ensuring high accuracy, repeatability, and efficiency in material removal.

CNC machines, such as lathes, mills, and routers, are programmed to carry out intricate tasks like drilling, milling, turning, and grinding. These machines interpret design data, typically provided in the form of 3D CAD models, to produce precise, custom-engineered parts with tight tolerances and consistent quality. CNC machining is widely used across industries such as aerospace, automotive, medical, and electronics, where precision and efficiency are critical.
