CNC machining service technology refers to a technology that uses digital instructions composed of numbers, words and symbols to realize the motion control of one or more mechanical equipment. CNC machining services generally use general-purpose or special-purpose computers to realize digital program control. Therefore, CNC machining services are also called computerized numerical control (CNC), which is abbreviated as CNC. It is generally called CNC abroad, and the concept of NC is rarely used. . It usually controls the mechanical quantities such as position, angle, speed and the switch quantity related to the flow of mechanical energy.
The production of CNC machining services depends on the emergence of data carriers and data operations in binary form. In 1908, a perforated metal foil interchangeable data carrier came out; at the end of the 19th century, a control system that used paper as a data carrier and had auxiliary functions was invented; in 1938, Shannon performed fast data calculation and transmission at the Massachusetts Institute of Technology in the United States. Laid the foundation of modern computers, including computer digital control systems. CNC machining service technology is developed in close integration with machine tool control. In 1952, the first CNC machining service machine came out, which became an epoch-making event in the history of the world machinery industry and promoted the development of automation.
