The hottest machine tool industry is a new way of

the logic of taking the intelligent road

intelligent manufacturing provides a historic opportunity for the leapfrog development of China's manufacturing industry. The new generation of intelligent manufacturing technology formed by the deep integration of the new generation of artificial intelligence technology and advanced manufacturing technology has become the core driving force of the new round of industrial revolution. Zhou Ji, an academician of the Chinese Academy of engineering, said in his speech "towards a new generation of Intelligent Manufacturing" at the Symposium on Intelligent + CNC new generation AI CNC systems and intelligent machine tools held in Beijing on April 16. The former president of the Academy of Engineering believes that with the rapid development and extremely rapid popularization and application of information technologies such as Internet, cloud computing and big data, the strategic breakthrough focused on the new generation of artificial intelligence (ai2.0) has made the new generation of artificial intelligence become the core technology of the new round of scientific and technological revolution, and the machine tool known as the industrial mother machine will benefit from artificial intelligence technology, which will fundamentally change people and information systems, From giving people fish to giving people fish. The new generation of intelligent machine tools can realize autonomous perception, autonomous learning, autonomous optimization and decision-making, autonomous control and implementation, greatly improve the machining quality and efficiency of machine tools, and reduce costs. It is a typical product of the fourth industrial revolution. Zhou Ji explained

from numerical control to intelligence, the path of change in the machine tool industry is not only the natural requirement of the general trend of technological development, but also the inevitable response of the industry to the current high-quality economic development. According to the "analysis of the economic operation of the machine tool industry in 2018" released by China Machine Tool Association in March, although the overall development of China's machine tool industry was stable in 2018, the demand in 3C consumer electronics and automotive manufacturing, which are closely related to the demand side of machine tool CNC systems, slowed down. The body structure represented by new energy vehicles was lightweight, and high-strength demand became the mainstream. 3C product processing also moved from metal processing to glass Ceramic processing, the demand of downstream industries for precision parts, has led the machine tool industry to become intelligent and high-precision

difficulties in taking the road to intelligence

empowering with intelligence is not a smooth path. According to Liu Qiang, a professor at Beijing University of Aeronautics and Astronautics, intelligent machine tools have three basic common problems 8 Weight specification: 40kg × 4、30kg × 3、20kg × 3、10kg × 3、5kg × 2 information, state perception and data processing, machine tool information system human communication protocols and interfaces, and intelligent analysis and control algorithms. The challenge faced by CNC machine tools in the industrial 4.0 era is the processing of new materials. The higher quality of products and the energy loss of 300 Joule pendulum should not be greater than 1.5 joules, and the energy loss of 150 Joule pendulum should not be greater than 0.75 joules. The demand for higher efficiency. To this end, he believes that the future manufacturing industry is facing four new changes: from a single manufacturing scenario to a variety of mixed manufacturing scenarios, from experience based decision-making to evidence-based decision-making, from solving visible problems to avoiding invisible problems, and from control based machine learning to deep learning based on rich data. This requires CNC machine tools to be intelligent. Liu Qiang believes that the above three basic common problems need to be solved to become an intelligent machine tool

the current intelligent machine tools only realize some simple perception, analysis, feedback and control, which is far from reaching the level of replacing human mental labor. The key is that there is no revolutionary technological breakthrough in autonomous learning. Due to the over reliance on human experts, the modeling and data analysis of high-end products rely on import theory, which leads to the difficult and slow accumulation of knowledge, and ultimately leads to the lack of adaptability and effectiveness of intelligent machine tools. Chenjihong, director of the national numerical control system engineering technology research center of Huazhong University of science and technology, said

how to overcome difficulties and let CNC plug in the wings of intelligence? In addition to being the director of the national numerical control system engineering technology research center, Chen Jihong, who is also the chairman of central China numerical control Co., Ltd., introduced the exploration and practice of central China numerical control in the new generation of artificial intelligence numerical control systems and intelligent machine tools to the guests. It is reported that based on the concept machine of the new generation of intelligent CNC system released in 2018, Huazhong CNC has developed the first Huazhong 9 industrial prototype of the new generation of artificial intelligent CNC system equipped with AI chips. This prototype has four intelligent characteristics of perception and interconnection learning, modeling optimization, decision control and execution, and contains the intelligent application app and intelligent functions of the new generation of artificial intelligence technology. The new generation of artificial intelligence control system of central China CNC was also released for the first time at this meeting

suggestions on taking the road of intelligence

the machine tool industry needs to take the road of intelligent manufacturing according to the factory conditions. Li Dongru, Deputy Secretary General of the China Machinery Industry Federation, said that due to the current size of China's machine tool enterprises, they need to consider their own reality in the process of transformation and upgrading. At the same time, she believed that enterprises should comprehensively consider the performance, quality and price of products in the process of intellectualization, and should be in line with the actual route of enterprises. Liu bingye, the former director of Beijing Machine Tool Research Institute, suggested that the CNC system plays a very important role in the process of machine tool enterprises moving towards intellectualization and towards the middle and high-end. However, we should pay attention to laying a good foundation. In addition to doing a good job in the control system, we should also do the parts. From the perspective of the future demand for ultra precision parts, we should have the spirit of craftsman to make machine tool products, and we should make the parts to the extreme, and we can't take shortcuts

the machine tool industry is taking a new route of transformation with intelligence.
