CNC stands for Computer Numerical Control. It converts the design produced by Computer Aided Design software (CAD) into numbers.

Definition

CNC means Computer Numerical Control. This means a computer converts the design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material.
