![]() ![]() The axes are given simple names such as X, Y and Z (based on the Cartesian Coordinate System).Ī CNC machine must be able to communicate with itself and the machinist to operate. Most CNC machines are able to move in three controlled directions at once. It was a major advance in the ability of machines to reproduce complex part machining steps more accurately without human intervention or variability.Ī CNC machine uses mathematics and coordinate systems to process information of what to move, to where, and how fast. CNC technology was developed in the United States in the 1950's for the United States Air Force by metalworking machine tool builders. A CNC machine uses a stream of digital information (code) from a computer to automatically execute a series of machining operations that CNC machines offer to increase productivity and flexibility. CNC stands for Computerized Numerical Control.
