Intelligent machine tools promote manufacturing into the core age

Machine tools, as one of the most important equipments in the processing and manufacturing of current industrial equipment, are constantly moving toward intelligence. CNC machine tools have created a precedent for the integration of precision manufacturing technology and related technologies, computer software and hardware technologies, and compatible with network technology, and started the development of human intelligent production tools. When the numerical control machine gradually has logic judgment and teaching function through the numerical control device, this intelligent characteristic has begun to receive more attention.

Intelligent machine tools are machines that make decisions and decisions about the manufacturing process. After understanding the entire process of manufacturing, intelligent machine tools can monitor, diagnose and correct various types of deviations that occur 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 the user to know the remaining usage time and replacement time.

The emergence of intelligent machine tools has created the conditions for future equipment manufacturing to realize full-scale production automation. The intelligent machine tool can improve machining precision 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 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 outside the machine, and can 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 hold a large amount of information, store, analyze, process, judge, adjust, optimize, and control various information. Intelligent machine tools also have important functions, such as: fixture database, dialogue programming, tool path inspection, process machining time analysis, start-up time status analysis, actual processing load monitoring, processing navigation, adjustment, optimization, and adaptive control.

The development of information technology and its integration with traditional machine tools have made the machine tool development in the direction of digitization, integration and intelligence. The application space for digital manufacturing equipment, digital production lines, and digital factories will become increasingly large. Intelligent technology is used to implement intelligent decision-making, process adaptation control, error compensation intelligent control, and complicated curved surface machining movement trajectory for multi-information fusion. Optimization control, fault self-diagnosis, intelligent maintenance and information integration will greatly improve the forming and machining precision and improve the manufacturing efficiency. CNC machine tools need to strengthen the intelligent judgment of information.

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

The intelligent control of the machine tool puts forward higher requirements on the numerical control system. This requires that the numerical control system not only has openness, inclusiveness, and certain secondary development features, but also needs the user to customize the functions of the numerical control system. Universality and forward-looking also raised higher expectations.

With the vigorous development of economy and science and technology, the improvement of people’s cultural quality and improvement of living conditions, in addition to the country’s strong support, the country’s gradual emphasis on security, more and more robots have gradually replaced many people in many industries. Work in the field. The era of industrial robots is ushering in its own spring. According to Luo Baihui, secretary-general of the International Mould and Metals and Plastics Industry Suppliers Association, foreign auto industry, electronic and electrical industries, construction machinery and other industries have used industrial robot automated production lines to ensure product quality and increase production efficiency, while avoiding a large number of Industrial accidents. The practice of industrial robots in nearly half a century in many countries around the world shows that the popularization of industrial robots is an effective means to realize automated production, increase social production efficiency, and promote the development of enterprises and social productivity. Robotics is a forward-looking and strategic high-tech field. Industrial robots automated production line complete sets of equipment has become the mainstream of automation equipment, the popularity of domestic robots is also sooner or later.

Although today's robots have not yet developed to a very high degree of intelligence, simple machine workers and machine assistants have gradually deepened 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 2015, one-third of ground combat will use robotic soldiers.

This triggered a sense of crisis in China and accelerated the pace of developing the robot industry. At the “2013 China Robot Industry Promotion Conference” held in early July of this year, Wang Weiming, Deputy Director of the Department of Equipment Industry of the Ministry of Industry and Information Technology, publicly stated that after researching the robot industry, “About promoting the development of industrial robot industry will be released soon. instructions". Robots will become intelligent and universal, and will soon revolutionize the manufacturing industry. It can thus be seen that the era of robotics in industry is embarking on the grand stage of China's industrial development.

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

The "12th Five-Year Plan for High-end Equipment Manufacturing Industry Development", hereinafter referred to as "Planning", has begun to implement the transformation of smart equipment development and satellite and application development projects. This shows that the development plan of high-end equipment manufacturing industry has entered a substantive operation level.

As an important part of the strategic emerging industry, the development strategy of the “Twelfth Five-Year Plan” for high-end equipment manufacturing industry is to break through key points in five directions: aviation equipment, satellites and applications, rail transit equipment, marine engineering equipment and intelligent manufacturing equipment. The goal of the "Plan" is that by 2015 the sales value of high-end equipment will account for more than 20% of the equipment manufacturing industry, and it is expected that the annual sales value will reach 6 trillion yuan.

The data shows that the current industry scale of smart equipment is about 300 billion yuan, the market is mostly monopolized by foreign manufacturers, the market share of domestic manufacturers is low, intelligent instrumentation and control systems are 10%, industrial robots and special equipment are 20%, and mid-range CNC 20% for machine tools and 1% for high-end CNC machines. The goal of the “Planning” is that by 2015, sales revenue will reach 1 trillion yuan. The domestic market share of high-end smart equipment and basic manufacturing equipment required by key national economic industries will reach 50%; sales revenue will reach 2 trillion yuan in 2020. Yuan, the domestic market share reached 70%.

The first batch of funds used to subsidize smart equipment manufacturing has been released. The first batch of smart manufacturing equipment for the implementation of subsidy funds had 19 projects, and the state subsidy funds were 950 million yuan, which has now officially started. In particular, to support smart manufacturing equipment companies in expanding their markets, the country will allocate the first set of subsidy funds to subsidize funds of up to 25% to 50% of the product sales price.

According to reports, the "Planning" is expected by 2015, the annual sales value of high-end equipment manufacturing industry will be more than 6 trillion yuan. Prior to this, Zhang Xiangmu once expressed similar views. He said, "We will strive to make the high-end equipment manufacturing industry a pillar industry of the national economy through 10 years of efforts, and the sales value will account for more than 30% of the equipment manufacturing industry. The domestic market for equipment is more than 25%."

Machine Tool Industry Transformation Brings Robotics Technology to a New Trend

Machine tool companies have also begun to introduce robots into machine tools. Robots have become a general trend. In the transition from digitization to intelligentization, the manufacturing industry has higher requirements on the performance of equipment components, including precision and surface quality. Especially in some high-tech industries, such as aerospace and communications. The change of technology demand in the downstream market has brought new challenges to the development of the CNC machine tool industry. If the technical development of CNC machine tools can adapt to the needs of the transformation and upgrading of the manufacturing industry, it can play a promoting role, and vice versa, it will restrict its development.

An American expert put forward this year: "When we combine artificial intelligence, robotics, and digital manufacturing technologies, a manufacturing revolution will take place. It will enable American entrepreneurs to start factories and build a variety of This way, how can China compete with us? The United States is destined to regain leadership in the manufacturing industry, and it will soon be China’s concern to worry about it.” American scholars put forward the three major technical phases of declaring war on the Chinese manufacturing industry. Combined with the resulting manufacturing model, it can be called manufacturing intelligence, that is, smart manufacturing.

At present, most domestic machine tool companies are concerned about how to make the company bigger. There are thousands of people and tens of thousands of people. And foreign companies are more eager to lead the technology, that is to make their own products in the manufacture of other products indispensable. At present, the competition mechanism of Chinese machine tool companies mainly depends on price and quantity, and lacks core technologies. With the increase in labor, raw materials and other costs, corporate profits will become increasingly thin. Therefore, the competition mechanism needs to be changed.

The key application of industrial robots is motion control, and motion control is an important factor in ensuring the accuracy of machine tools. From this perspective, the correlation between machine tool manufacturing and robot manufacturing technology is very large. Therefore, the enthusiasm of machine tool companies to intervene in the manufacture of industrial robots has increased in recent years.

Not only is the CNC system manufacturing company, machine tool companies are also very popular in robotics. Kan Xiyou, chairman of Shenyang Machine Tool Group, which has the largest domestic sales of machine tools, also stated that the Shenyang Group has the experience in developing the Feiyang CNC system and is preparing to cut into the industrial robot manufacturing field and develop industrial robot products.

It can be seen that whether it is the introduction of foreign robots or the development of domestic industrial robots, smart entrepreneurs have already targeted the broad prospects of its integration with the machine tool industry!

Talent cultivation is the key to the development of the robot industry

Tang Zhimin, secretary of the Party Committee of the Chinese Academy of Personnel Sciences, said that under the strong support of the national policy, the robotics industry will surely usher in explosive growth, and the new industry will bring new employment opportunities.

At present, the competition for robotic projects has become a contest between emerging manufacturing industries. In the domestic manufacturing industry, from the demand for the transformation of labor costs and automated production, the industrial robot industry has entered a period of explosive growth. The robotic industrial bases in Chongqing, Tianjin, Kunshan, Qingdao, Shenyang, and Zhongshan have mushroomed.

At present and for a period of time in the future, the pressure on the total employment of college graduates in our country is still relatively large, the structural contradictions are still quite prominent, and the employment situation is rather grim. This year's document issued by the State Council on college graduates clearly puts forward the role of strategic emerging industries, high-tech industries, modern service industries, and modern agricultural development in the promotion of college graduates, which also includes smart Internet of Things and Robot industry.

How many college students can bring entrepreneurship and employment opportunities to the new industry? Vice President Shen Hongru of Ziguang Youlan stated that the Internet of Things is beyond the communication between people and information on the Internet, and it extends people-to-people and material-to-human communication. With the connection between things, you can cook rice cookers in your company's home, turn on air conditioners in your home, let water heaters put water for you, see if your child is learning or playing games... all this The core of the center is a robot, and related product development, production, marketing, shopping guide, and after-sales service require college students. In the next five years, with the rapid development of this industry, it is expected to provide at least 200,000 related jobs.
