Numerical control technology and numerical control equipment are an important foundation for the industrial modernization of various countries. There is still a certain gap between my country's numerical control technology and the world's advanced countries. Therefore, it is very important to understand the development of numerical control technology at home and abroad for the development of my country's numerical control field. Numerical control technology (referred to as ie) has been used in production for more than 20 years. It has caused qualitative changes in the traditional manufacturing industry, especially in recent years. The development of microelectronics technology and computer technology has brought technology new vitality. CNC machine tools are the mainstream equipment in the modern manufacturing industry, an important symbol reflecting the technical level of modern machine tools and the technological level of modern machinery manufacturing, and strategic materials related to the national economy, the people's livelihood, and the construction of cutting-edge national defense. Therefore, all industrialized countries in the world have taken major measures to develop their own numerical control technology and their industries.

The development trend of CNC machine tools:

♦ High speed

With the rapid development of industries such as automobiles, aviation, and transportation rails, as well as the application of new materials such as composite materials, the requirements for high-speed machining of CNC machine tools are getting higher and higher.

♦ High precision

The precision requirements of CNC machine tools are now not limited to static geometric precision, and more and more attention has been paid to the movement precision, thermal deformation and vibration monitoring of machine tools.

♦ Intelligent control

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

♦ Extremes (upscaling and miniaturization)

The development of aviation and aerospace industries and the large-scale equipment of basic industries such as energy require the support of large-scale CNC machine tools with good performance. The ultra-precision machining technology and micro

Nanotechnology is the strategic technology of the century, and it is necessary to develop new manufacturing techniques and equipment that can adapt to micro-small size and micro-nano machining precision, so micro-machine tools include

The demand for micro-cutting (turning, milling, grinding) machine tools, micro-electrical processing machine tools, micro-laser processing machine tools and micro-presses is gradually increasing.

♦ Networked information exchange

For enterprises facing fierce competition, it is necessary to enable CNC machine tools to have two-way, high-speed networking communication functions to ensure smooth flow of information among various departments in the workshop.

Resistance is very important.

♦ New functional components

In order to improve the performance of CNC machine tools in all aspects, the application of new functional components with high precision and high reliability has become inevitable.

♦ High reliability

Compared with traditional machine tools, CNC machine tools have increased the CNC system and corresponding monitoring devices, etc., and applied a large number of electrical, hydraulic and electromechanical devices, which is easy to cause failures.

Fluctuation and interference are extremely detrimental to the reliability of CNC machine tools, and the parts processed by CNC machine tools are relatively complex, and the processing cycle is long, requiring an average time between failures

More than 10,000 hours. In order to ensure the high reliability of CNC machine tools, it is necessary to carefully design the system, strictly manufacture and clarify reliability goals, and through maintenance analysis

failure modes and identify weak links.

♦ Green processing

With increasingly stringent environmental and resource constraints, the greening of manufacturing and processing is becoming more and more important, and China's resource and environmental problems are particularly prominent.
