Machine tools, as one of the most important equipment in current industrial equipment manufacturing, are constantly moving towards intelligence. CNC machine tools have pioneered the integration of precision manufacturing technology and related technologies, computer software and hardware technologies, and are compatible with network technologies, and have started the development of human intelligent production tools. After the numerical control machine tool gradually equipped with the logical judgment and teaching function through the numerical control device, this intelligent characteristic began to receive more attention.

Intelligent machine tools are machines that can make judgments and decisions about the manufacturing process. After the intelligent machine tool understands the entire manufacturing process, it can monitor, diagnose and correct various deviations in the production process. And can provide solutions for the optimization of production. In addition, the remaining life of the cutting tools, spindles, bearings and guides used can be calculated, allowing users to know the remaining usage time and replacement time.

The emergence of intelligent machine tools has created conditions for the equipment manufacturing industry to achieve full production automation in the future. Intelligent machine tools can improve the machining accuracy and efficiency of the machine tool by automatically suppressing vibration, reducing thermal deformation, preventing interference, automatically adjusting the amount of lubricant, and reducing noise. For the further development of integrated manufacturing systems, the improvement of the automation level of a single machine tool can greatly reduce the workload of people in managing machine tools.

Intelligent machine tools enable people to have more energy and time to solve complex problems other than machine tools, and further develop intelligent machine tools and intelligent systems. The development and innovation of the CNC system has played an extremely important role in the intelligentization of machine tools. It can contain a large amount of information, and store, analyze, process, judge, adjust, optimize, and control all kinds of information. Intelligent machine tools also have important functions, such as: fixture database, interactive programming, tool path inspection, process time analysis, start time status analysis, actual processing load monitoring, process navigation, adjustment, optimization, and adaptive control.

The development of information technology and its integration with traditional machine tools have made machine tools develop in the direction of digitization, integration and intelligence. Digital manufacturing equipment, digital production lines, and digital factories will have more and more application space; and intelligent technology will be used to implement intelligent decision-making, process adaptive control, error compensation intelligent control, and complex curved surface machining trajectory under the optimization of multiple information fusion Functions such as optimized control, fault self-diagnosis and intelligent maintenance, and information integration will greatly improve forming and machining accuracy and increase manufacturing efficiency. CNC machine tools need to strengthen the intelligent judgment of information.

Intelligent development is a more favorable development for constraint control. Intelligent technology can be used to monitor the status and response of processing in real time. Germany used to become constraint control, but later arrived in Japan and became intelligent control. This is actually a concept.

The intelligent control of the machine tool places higher requirements on the numerical control system. This requires that the numerical control system not only has openness, inclusiveness, and certain secondary development characteristics, but also requires the user to personalize its functions. Universality and forward-looking also set higher expectations.

 With the vigorous development of economy and science and technology, the improvement of people's cultural quality and the improvement of living conditions, in addition to the strong support of the state, the state has gradually attached importance to safety, and more and more robots have gradually replaced people in many industries. Field of work. The era of industrial robots is ushering in its own spring. According to the investigation by Luo Baihui, Secretary General of the International Mold, Metal & Plastic Industry Suppliers Association, foreign automotive industries, electronics and electrical appliances, construction machinery and other industries have used industrial robot automated production lines to ensure product quality and improve production efficiency, while avoiding a large number of Work accident. The use of industrial robots in many countries in the world for nearly half a century has shown that the popularity of industrial robots is an effective means to achieve automated production, improve social production efficiency, and promote the development of enterprise and social productivity. Robotics is a forward-looking and strategic high-tech field. The complete set of industrial robot automated production line equipment has become the mainstream of automation equipment, and the popularity of domestic robots is sooner or later.

Although today's robots have not developed to a very intelligent level, simple robot workers and machine assistants have gradually penetrated into the industrial field, and people are increasingly relying on advanced technology to produce and live. According to sources, the US Congress has stipulated that by 2020, one-third of ground combat will use robotic soldiers.

This triggered a sense of crisis in China and accelerated the pace of development of the robot industry. At the "2019 China Robot Industry Promotion Conference" held in early July this year, Wang Weiming, deputy director of the Equipment Industry Department of the Ministry of Industry and Information Technology, publicly stated that after investigation of the robot industry, the "About instructions". Robots are becoming intelligent and universal, which will soon revolutionize the manufacturing industry. It can be seen that the era of robotics in industry is grandly on the stage of China's industrial development.

High-end equipment planning to vigorously support the robot application market will blossom

The "Twelfth Five-Year Plan for the Development of High-end Equipment Manufacturing Industry" hereinafter referred to as "Planning" has been implemented before the development of intelligent equipment development and transformation, satellite and application development projects, which indicates that the development plan for high-end equipment manufacturing industry has entered a substantial operational level.

As an important part of the strategic emerging industry, the development ideas of the high-end equipment manufacturing industry during the "Twelfth Five-Year Plan" period are to break through from five major directions, namely aviation equipment, satellites and applications, rail transportation equipment, marine engineering equipment, and intelligent manufacturing equipment. The "Plan" proposes that by 2020, the sales output value of high-end equipment will account for more than 20% of the equipment manufacturing industry, and the annual sales output value is expected to reach 6 trillion yuan.

Data show that the current industrial scale of intelligent equipment is about 300 billion yuan. The market is mostly monopolized by foreign manufacturers. The domestic market share of domestic manufacturers is low. Intelligent instrumentation and control systems are 10%. Industrial robots and special equipment are 20%. Mid-range CNC 20% for machine tools and 1% for high-end CNC machines. The "Planning" aims to achieve sales revenue of 1 trillion yuan by 2020, and the domestic market share of high-end intelligent equipment and basic manufacturing equipment required by key industries of the national economy will reach 50%; sales revenue will reach 2 trillion yuan by 2020. Yuan, the domestic market share reached 70%.

The first funds to subsidize the manufacture of smart equipment have been released. The first batch of smart manufacturing equipment to implement subsidy funds has 19 projects, and the state subsidy fund of 950 million yuan has now officially started. In particular, in order to support smart manufacturing equipment companies to expand their markets, the state will allocate the first set of subsidy funds, up to 25% to 50% of the product sales price.

According to reports, the "Plan" predicts that by 2020, the annual sales output value of the high-end equipment manufacturing industry will exceed 6 trillion yuan. Previously, Zhang Xiangmu also expressed a similar view. He said, "Strive to make high-end equipment manufacturing industry a pillar industry of the national economy through about 10 years of hard work. Equipment domestic market satisfaction rate exceeds 25% "

Transformation of the machine tool industry

Machine tool companies have also begun to introduce robots into machine tools. Robots have become the general trend. In the process of digitalization and intelligent transformation, manufacturing industries have higher requirements for the performance of equipment components, including precision and surface quality. Especially in some high-tech industries, such as aerospace and communications. The change in technology demand in the downstream market poses new challenges to the development of the CNC machine tool industry. If the technological development of CNC machine tools can meet the needs of the transformation and upgrading of the manufacturing industry, it can play a driving role, otherwise it will restrict its development.

An American expert put forward this year: "When we combine artificial intelligence, robotics and digital manufacturing technology, a manufacturing revolution will occur. It will enable American entrepreneurs to start local factories and produce a variety of Products. In this way, how can China compete with us? The United States is destined to regain leadership in manufacturing, and it is time for China to worry about it. The combined manufacturing model can be called intelligent manufacturing, that is, intelligent manufacturing.
