CNC: A simple definition In the simplest terms, Computer Numerical Control allows for the automation of machine tools. Rather than the manual control of a cutting instrument, or even mechanical cutting to a set template, in CNC the computer is fully responsible for moving the cutting heads on a lathe, the wire on an EDM, or the bits on a mill.
