What is CNC Technology? How much it will affect the development of society in the future

1. High speed

With the rapid development of automobile, national defense, aviation, aerospace and other industries and the application of new materials such as aluminum alloy, the requirements for high-speed CNC machine tool processing are getting higher and higher.

2. High precision.

The requirements for the accuracy of CNC machine tools are no longer limited to static geometric accuracy, and more and more attention is paid to the motion accuracy, thermal deformation and vibration monitoring and compensation of machine tools.

3. Functional compounding.

Process compound machine tools, such as multi-sided and multi-axis simultaneous machining compound machine tools and double-spindle turning centers. The use of composite machine tools for processing reduces the auxiliary time of workpiece loading and unloading, replacing and adjusting tools, as well as the error in the intermediate process.

It improves the machining accuracy of parts, shortens the production cycle of product preparation, improves production efficiency and the manufacturer's market response ability, and has obvious advantages compared with the traditional production method of process dispersion.

4. Intelligent control.

With the development of artificial intelligence technology, in order to meet the development needs of manufacturing production flexibility and manufacturing automation, the intelligence of CNC machine tools is constantly improving.

Numerical control technologyIt is composed of three parts: machine tool body, numerical control system and peripheral technology.

The machine tool body is mainly composed of basic parts such as bed, column, guide rail, workbench and supporting parts such as tool holder and tool magazine.

The numerical control system consists of input and output equipment, computer numerical control.

Computer numerical control, CNC) device, programmable controller.

Programmable Logic Control, PLC) and spindle servo drive device, feed servo drive device and measuring device. Among them, the computer numerical control device is the core of the numerical control system.

Peripheral technologies mainly include tool technology (mainly referring to tool systems), programming technology and management technology.

The new trend of high-speed development, the new trend of precision machining, the new trend of open development, and the new trend of compound development.

As the core of the current advanced manufacturing technology, CNC technology.

It has many advantages, such as the use of soft hole components to change the way or process of information processing, without changing the mechanical and electronic devices, the speed of the number can also use the difference in word length to represent information, but also to complete logical and mathematical calculations on digital information. Therefore, CNC technology is widely used in the control of machine tools and robots.

With the wide application of CNC technology in China's industrial production, China's manufacturing capacity and in the international market of Mushou.

The competitiveness of the company has been significantly enhanced.

1.CNC is the abbreviation of digital control, and CNC technology is a method of using digital information to control mechanical movement and machining process.

2.CNC usually uses a specialized computer, the operation instructions are represented in numerical form, and the machine equipment works according to a predetermined program.

Tong no numericalcontrol): represents the old, original CNC technology.

Computer Numerical Control Technology – New Edition, the preferred abbreviated form of numerical control.

5.Digital control is an automatic slag control technology developed in modern times, and the national standard (GB8129-87) defines it as "a method of controlling the movement of machine tools and their processing process with digital signals".

1) Blue-collar layer.

CNC operation technician: proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools, understand automatic programming and simple maintenance and repair of CNC machine tools. It is suitable for the organization and training of secondary vocational schools.

This type of personnel is in high demand in the market and is suitable as a CNC machine tool operator in the workshop. However, due to its relatively simple knowledge, its salary will not be much higher.

2) Gray collar layer.

CNC programmer: master the knowledge of CNC machining technology and the operation of CNC machine tools, master the design and manufacturing expertise of complex molds, and be proficient in 3D CAD CAM software, such as UG, PROE, etc.; Proficient in CNC manual and automatic programming technology; It is suitable for the organization and training of higher vocational colleges.
