How Do CNC Machines Work?

CNC machines usually feature a version of a CAD software program. A CAD program, or computer-aided design, is software which allows you to draw what you want to cut. The drawing is either 2D or 3D and when completed it a creates a code for the CNC machine to read.

CNC machines work by following co-ordinates along axis. Basic machines move along one or two axis, but advanced machines, and those creating 3D items, will move along three axis. The machine’s tools follow thousands of co-ordinates, cutting and shaping as they move.

Before a CNC machine begins its first task, a trial run is conducted. This trial run is referred to as cutting air and is incredibly important as any mistakes could result in a damaged machine or part.
