How does CNC machining work?

CNC machining works by taking information entered into a computer and converting the data into electrical signals. These signals are transmitted to the motors within the CNC machining centre, and control the various mechanisms contained within it. The components of a CNC machining centre are able to move in extremely small increments, enabling the tools to carry out very intricate processes on the work piece – far more delicately than would be possible by hand.
