Quizplus · Accepted Answer

Numerical control (NC) refers to the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually by hand wheels or levers, or mechanically automated by cams alone. It is a method for controlling machine tools through the use of instructions encoded in a digital form, which applies to a wide range of machinery, not just milling machines.
