Numerical control technology refers to the technology of using digital instructions composed of numbers, words and symbols to realize the action control of one or more mechanical equipment. It usually controls mechanical quantities such as position, angle, velocity, etc., as well as switching quantities related to the direction of mechanical energy flow. The generation of numerical control depends on the emergence of data carriers and binary form data operations.
In 1908, perforated metal sheet interchangeable data carriers were introduced; At the end of the 19th century, a control system with paper as a data carrier and auxiliary functions was invented; In 1938, Shannon carried out rapid data computing and transmission at the Massachusetts Institute of Technology in the United States, laying the foundation for modern computers, including computer numerical control systems. CNC technology is developed in close combination with machine tool control. In 1952, the first CNC machine tool came out, which became an epoch-making event in the history of the world's machinery industry and promoted the development of automation.
Now, numerical control technology is also called computer numerical control technology, which is currently the technology that uses computers to realize digital program control. This technique uses a computer to perform the control function of the equipment according to a pre-stored control program. Because the computer is used to replace the original numerical control device composed of hardware logic circuits, the realization of various control functions such as storage, processing, calculation, and logic judgment of input data can be completed by computer software.
Trouble, thanks!

CNC spinal nucleus is the abbreviation of digital control, and CNC technology is a method of using digital information to control mechanical movement and machining process.
There were two versions in the early days:
NC (NumericalControl): Represents the old, original numerical control technology.
CNC (ComputerizedNumericalControl): Computer Numerical Control Technology - New Edition, the preferred abbreviated form of numerical control.
NC may be CNC, but CNC by no means refers to the old CNC technology.
After the 1970s, the hardware circuit components were gradually replaced by a special computer and called the computer numerical control system, which is generally a special computer and equipped with an interface circuit, which can realize the control of the action of multiple CNC equipment. Therefore, the current CNC is generally CNC (computer numerical control), and the concept of NC is rarely used anymore.
Numerical control technology is also called computer numerical control technology (CNC, computerizednumericalcontrol), which is the technology that uses computers to achieve digital program control. This technology uses a computer to perform the operation sequence logic control function of the movement trajectory of the equipment and the peripherals according to the pre-stored control program.
Because the computer is used to replace the numerical control device composed of the original hardware logic circuit, the realization of various control functions such as storage, processing, operation and logic judgment of input operation instructions can be completed by computer software, and the microscopic instructions generated by processing are transmitted to the servo drive device to drive the motor or the hydraulic actuator to drive the equipment to run.
The CNC major is to cultivate application-oriented senior technical talents who master the basic theories and basic knowledge of CNC technology and application majors, and can be engaged in production, management, product marketing, equipment maintenance and other work in the front line of production.

Numerical control technology, also known as computer numerical control technology, is the use of computers to achieve digital program control technology. In this technology, various control functions such as storage, processing, operation and logical judgment of input data are realized by computer software. Compared with the previously used hardware logic circuits, the device has the advantages of small size, simple structure, stable operation, strong reliability and high precision, and is widely used in various fields such as braiding and cracking, mechanical design, parts processing, circuit control and so on.
It is the abbreviation of numerical control, which is an automated method of programming and controlling a certain working process with the help of numbers, characters or other symbols.
1. CNC usually uses a special computer, the operation instructions are expressed in digital form, and the machinery and equipment work according to the predetermined program. NC (Numerical Control): It stands for the ancient and primitive numerical control technology.
CNC (Computer Numerical Control): Computer Numerical Control Technology - New Edition, the preferred abbreviation for CNC.
2.Digital control is an automatic control technology developed in modern times. The national standard (GB8129-87) defines it as "a method for controlling the movement of a machine tool and its machining process with a digital signal".

Employment direction of CNC major:
1. The employment of CNC majors in industrial enterprises is engaged in CNC programming, the use, maintenance and technical management of CNC equipment, and the sales and after-sales service of CNC equipment.
CNC major is mainly oriented to machinery, mold, electronics, electrical, light industry and other industries, can be engaged in product design and processing, CNC programming, CNC machine tool operation, CNC common CAM software multi-axis machining, CNC equipment debugging and maintenance and other related work.
2. The employment of CNC major can be oriented to high-end equipment manufacturing industries such as power generation equipment manufacturing, military industry, aerospace industry, shipbuilding, data equipment manufacturing, etc., and is engaged in CNC machine tool operation, data processing program preparation, data processing technology preparation, product quality inspection, on-site management, production scheduling, CNC equipment sales and after-sales service.
3. The employment of CNC majors can be CNC programmers. Many machining companies use automatic programming to generate CNC machining programs, so they need to learn CAM software. Different units use different CAM software, and there are many types, but the processing methods are generally similar, but being a CNC programmer is very demanding and has great responsibilities, so it requires rich processing experience.
