Abstract :

Numerical Control (NC) refers to the method of controlling the manufacturing operation by means
of directly inserted coded numerical instructions into the machine tool.

Numerical control (NC) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to manually controlled via handwheels or levers, or mechanically automated via cams alone.
