What is CNC• Computer numerical control (CNC) is the
process of manufacturing machined parts.• Production is controlled and allocated by a
computerized controller.• A programmed path is loaded into the machine's

• It is the program of instructions in the NC control system.
• Each command specifies a position or motion that is to be accomplished by the work head relative to the workpart.
• The part program is prepared by a part programmer, a person who is familiar with the details of the programming language and also understands the technology of the processing equipment.
