Computer Numerical Control (CNC) is a computerized control system that automates the operation of manufacturing machinery, particularly in the field of machining. With the use of CNC technology, machines can be programmed to perform precise and complex tasks by following a set of instructions, typically in the form of a computer-aided design (CAD) file. The CNC system interprets these instructions and controls the movement of the machine’s tools to produce high-quality and accurate parts or products.
