CNC stands for Computer Numerical Control. It refers to the computerized automation of machine tools used in manufacturing, where pre-programmed software controls the precise movements and operations of machines such as mills, lathes, routers, and grinders to cut, shape, or create parts from materials like metal or plastic
. The process involves creating a computer-aided design (CAD) of the part, converting it into a program usually written in G-code, and then executing this program on the CNC machine to perform tasks with high accuracy and repeatability without manual intervention
. In summary, CNC is a manufacturing technology that automates the control of machining tools through computer programming to produce complex and precise components efficiently
