CNC Machining, also known as Computer Numerical Control Machining, uses computers to control machine tools such as mills, grinders, lathes, and routers in the manufacturing field, and can be used on three-dimensional plastic and metal parts when a high level of precision and/or repetition is needed. A customized computer program is programmed using the CNC machine language, G-code, and it controls all aspects of manufacturing such as speed, location, coordination, positioning, and velocity. [
