What is numerical control (NC or CNC)



&Nbsp& Nbsp; Numerical control is the abbreviation for numerical control, also known as numerical control. At present, numerical control generally uses general-purpose or specialized computers to achieve digital program control, so numerical control is also known as Computer Numerical Control (CNC), abbreviated as CNC. It is generally referred to as CNC abroad, and the concept of NC is rarely used. Below is a detailed explanation:

&Nbsp& Nbsp; Numerical Control (NC) refers to the technology of using numerical instructions composed of numbers, text, and symbols to control the movement of one or more mechanical equipment. It usually controls mechanical quantities such as position, angle, speed, and switch quantities related to the flow of mechanical energy. The emergence of CNC relies on the emergence of data carriers and binary data operations. In 1908, perforated metal sheet interchangeable data carriers were introduced; At the end of the 19th century, control systems with paper as the data carrier and auxiliary functions were invented; In 1938, Shannon conducted rapid data processing and transmission at the Massachusetts Institute of Technology in the United States, laying the foundation for modern computers, including computer digital control systems. Numerical control technology is closely integrated with the development of machine tool control. In 1952, the first CNC machine tool was introduced, becoming a groundbreaking event in the history of the world's mechanical industry and promoting the development of automation& Nbsp< Br/>
&Nbsp& Nbsp; Nowadays, CNC technology, also known as Computer Numerical Control, is a technology that uses computers to implement digital program control. This technology uses computers to perform control functions on devices based on pre stored control programs. Due to the use of computers to replace CNC devices composed of hardware logic circuits, various control functions such as storage, processing, operation, and logic judgment of input data can be achieved through computer software& Nbsp< Br/>
