The program is loaded onto the MCU, and a machine operator performs a test run without the raw material in place to ensure proper positioning and performance.
The program also contains the instructions and parameters the machine tool follows, such as the feed rate of materials and the positioning and speed of the tool's components.Įarly in the process, engineers create a computer-aided design ( CAD) drawing of the part to be manufactured and then translate the drawing into G-code. While G-code controls the movement and functioning of the machine, M-code controls the operation's external movements. The M-code language is also used in conjunction with G-code in CNC operations. With CNC, each object to be manufactured gets a custom computer program, usually written in an international standard language called G-code, stored in and executed by the machine control unit (MCU), a microcomputer attached to the machine. It can also be used to control nonmachine tools, such as welding, electronic assembly and filament-winding machines. Mills, lathes, routers, drills, grinders, water jets and lasers are common cutting tools whose operations can also be automated with CNC. What is computer numerical control (CNC)?Ĭomputer numerical control (CNC) is a manufacturing method that automates the control, movement and precision of machine tools through the use of preprogrammed computer software, which is embedded inside the tools.ĬNC is commonly used in manufacturing for machining metal and plastic parts.
