Instructions for numerical control machine (CAMS)

NC is a file extension for an instructions file format used by CAM machines such as a CNC milling machine.

NC files contain instructions to control the machine in its manipulation of a cutting tool, for example, as well as moving the medium, perhaps a blank aluminum block to create a 2D or 3D object such as an engine block.
