What is numerical control?

Numerical control is short for numerical control. Value? Control, NC for short. At present, CNC generally uses general or special computers to realize digital program control, so CNC is also called computer numerical control (computer? Value? Control? ) generally called CNC.

Numerical control refers to the technology that uses digital instructions composed of numbers, characters and symbols to realize the action control of one or more mechanical equipment. Usually control mechanical quantities such as position, angle and speed, as well as switching quantities related to the flow direction of mechanical energy. The appearance of numerical control depends on the appearance of data carrier and binary data operation. Numerical control technology is closely combined with machine tool control and developed. 1952, the first CNC machine tool came out, which became an epoch-making event in the history of the world machinery industry. Numerical control technology, also known as computer numerical control technology, is a technology that uses computers to realize digital program control. This technology uses a computer to execute the control function of the equipment according to the pre-stored control program. Because of the use of computers, control functions such as storage, processing, operation and logical judgment of input data can be realized by computer software.
