In CNC machining, the commonly used file formats are STEP and IGES. It is capable of controlling the speed of rotation and rate of the movement. G- Code is programmed in such a way that it controls the movement of a machine by adjusting the position of x, y, and z-axis. Alternate to G-Code, there are Heidenhain and Mazak also in use. The primary CNC programming language is G-Code. Each part of the machine requires its own CNC program.
A Computer Numerical Control (CNC) software enables to create programs to run a machine tool.
