Overview:
computer numerical control (CNC) refers specifically to a computer "controller" that reads instructions and drives the machine tool.
In modern CNC systems, end-to-end component design is highly automated using CAD/CAM programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine, and then loaded into the CNC machines for production.
