What Is CNC? CNC Machining is a manufacturing process where computers run programs that control how the machines will manufacture parts.. These CNC Programs using CNC Software can control everything from the motions the machine makes to spindle speed, turning coolant on or off, and much more. The computer language used to program CNC Machines is called "G-Code".
