How Do CNC Machines Work?
What is CNC? Computer Numerical Control (CNC) machines have dozens of business and manufacturing applications. CNC is used in everything from home embroidery machines to robotic arms in a manufacturing assembly plant. Any machine operated by a computer program can be considered a CNC machine. Most CNC machines are now programmed using CAD/CAM software. Programming the CNC Program a CNC machine by generating G and M codes that the machine understands. The G code is a Go code that tells the machine the precise movements, turns and cuts to make, while the M code turns fluids and other extra devices on and off. These codes are generated with a CAM, or Computer Aided Machining program. More often than not, the CAM program is a part of a CAD, or Computer Aided Design program where the parts are drafted into the computer to exact specifications. Loading the Code The G and M codes can be saved from the computer and stored on flash or floppy drives to be transferred to the CNC machine. In envir
