Intelligent manufacturing system and research achievements and existing problems. Key words: intelligent manufacturing, IMS, IMC, IMT. 1 main research contents and objectives There is no generally accepted definition of Intelligent Manufacturing in the world. A current definition is more common, intelligent 实用标准文档 文案大全 manufacturing technology refers to the various links in the manufacturing industry, in a highly flexible and highly integrated manner to simulate intelligent manufacturing activities of human experts through the computer. Therefore, the research and development of intelligent manufacturing is the mechanical object the main research and development of manufacturing enterprises, there are two objectives: the overall intelligence throughout the manufacturing work, in the actual manufacturing system is put forward for the first time to replace the human machine intelligence department of mental labor as the main target, and strong adjustment process of production and operation enterprises a wide range of self organization ability; the information system and The integration and sharing of intelligence building, emphasis on integrated automation intelligent. At present, the research direction of IMT and IMS from the initial development of application of artificial intelligence in the field of manufacture to IMS today, the scope of research subject analysis from only one enterprise in the market, product design, production planning, manufacturing and processing, process control, information management, maintenance and other technical aspects of the automation equipment, integrated development to today's world within the scope of the whole manufacturing environment and self organization ability, including the manufacture of intelligent processing technology, self-organizing processing unit, self-organized robot, intelligent production management information system, multi-level. Contention control network, global communication and operation network 2 artificial intelligence and IMT, IMS The study of artificial intelligence to start manufacturing machine failed to get rid of biological thought, namely “intelligent machines“. 实用标准文档 文案大全 The “independent“ system as the goal of the research route, has seriously hindered the progress of artificial intelligence research. Many scholars have been aware of this, Tsien Hsueshen from the computer point of view, put forward the intelligent system the concept of combining with computer. At present, foreign invested heavily in multimedia and virtual technology research, and Japan's fifth generation intelligent computer development plan ran aground and other examples, is the goal of the research on the system of intelligent change proof. The application of artificial intelligence technology in the field of Mechanical manufacturing involves market analysis, Product design, production planning, process control, quality management, material handling, equipment maintenance and other aspects. It is developed a variety of domain specific independent expert system, system or intelligent auxiliary system based on knowledge, the formation of a series of “intelligent island“. With the in-depth research and application, people gradually realize that the automation of future manufacturing should be the organic fusion machine system highly integrated and intelligent people, self organization to further enhance the ability to rely on the whole manufacturing system of manufacturing automation. How to improve the application scope of these “islands“ and asked in the actual manufacturing environment The ability to become a research focus of the people. At the end of 80s and early 90s, a through integrated manufacturing automation, a new generation of artificial intelligence, new manufacturing engineering: IMT and new generation manufacturing systems IMS computer science and technology talent shows itself development. An important difference in manufacturing in the field of artificial intelligence the application of IMT and IMS in IMS and IMT for the first time to replace part of the mental work in manufacturing as the research object, not only the “support“, in a certain range also need to be able to adapt to the surrounding environment independently, 实用标准文档 文案大全 To carry out the work. Four IMS CIMS and the development of the road is not Everything is going smoothly Today, CIMS development has encountered an impassable obstacle may be the beginning of CIMS put forward high request, it is also possible that CIMS itself is defective in some innate, today's CIMS is not in the world a few years before it has been paid great attention and extensive research. From the perspective of the development of CIMS, many researchers focus on computer integrated, from the current situation of science and technology, the performance of such an integrated system is very difficult to.CIMS as a single production line connecting the self The dynamic system is a kind of strategy, improve the efficiency of manufacture technology. It has a hierarchical information technology based network centralized structure. In spite of this hierarchical system with multiple levels of execution, but the main control facilities is still a major problem in computer center.CIMS is a heterogeneous environment for interconnection complexity must be. In the CIMS concept, the manual operation to operation and high degree of automation or semi automation integration is very difficult and expensive. In the further development of CIMS and application of today, people have gradually realized that, to make the CIMS really play the application efficiency and large area, there are two The big problem to be solved: the human status and functions in the system; in no great investment for technological transformation of the existing facilities can also be applied under the existing CIMS. CIMS concept is to solve these two problems. Not today, human and automation is one of the technical problems, can not be integrated together, the can choose to do, or is a full automatic production line of expensive, or manual operation, which is the lack of compatibility between human and manufacturing equipment, man-machine engineering is a more important consideration, consider compatibility should be reflected in the competition, skills and decision-making 实用标准文档 文案大全 ability. In the manufacturing process the role needs to be redefined And take it seriously. 3 material basis and theoretical basis of intelligent manufacturing The material basis of 3.1. intelligent manufacturing system: (1) CNC machine tools and machining center in the United States in 1952 successfully developed the first numerical control milling machine, so that the mechanical manufacturing industry a technological revolution (2) the computer aided design and manufacture improve the quality of the products and shorten the production cycle of the products, and change the traditional management mode of the whole production process (3) industrial control technology, combining microelectronics and mechanical industry, robot has created a new situation of industrial production, the production of significant changes in the structure, make the manufacturing process more flexible and expanded the scope of human work. (4) manufacturing system for the intelligent development of the manufacturing process In particular sectors, specific aspects of the “intelligent island“, such as expert system, knowledge based system and intelligent auxiliary system. (5) intelligent manufacturing system and computer integrated control 实用标准文档 文案大全 production system computer integrated manufacturing system, the concept of production from design to manufacturing, integrated and be directly facing the market for production, can be engaged in the size and diversification of production; in recent years, manufacturing technology has made great development and progress, it also brings a lot of new problems. CNC machine tools, automatic material system, computer control system, = robot has been widely used in the industrial company, more and more companies use the computer integrated manufacturing system (CIMS) “,“ flexible manufacturing system (FMS) “,“ factory automation (F A) “,“ multi target intelligent computer aided design (M1CAD) “,“ modular manufacturing and factory (MXMF), concurrent engineering (CE) “,“ intelligent control system (ICS) “and“ intelligent manufacturing (IM) “,“ intelligent manufacturing technology (IMT) “and“ intelligent manufacturing system (IMS) “and so on new terms. The advanced computer technology, control technology and manufacturing technology to the product, put forward new challenge process and system designers and management personnel, design and management of the traditional methods can not effectively solve the problem of modern manufacturing system. To solve these problems, need to use the modern Tools and methods, such as artificial intelligence (AI), provide a set of tools for solving complex industrial problems Theoretical basis of 3.2. intelligent manufacturing technology Intelligent manufacturing technology is a new manufacturing concept and implementation mode. Its core feature emphasizes the whole manufacturing system's overall “intelligent“ or “self organization“ and “individual autonomy“. The “intelligent manufacturing international cooperation research project JIRPIMS“ clearly pointed out: “intelligent 实用标准文档 文案大全 manufacturing system is a kind of intelligent through in the manufacturing process, and the intelligent activities and intelligent machines of organic integration, the entire manufacturing process will be in order, product design, production and all aspects of the market in a flexible manner is integrated to maximize the productivity of the advanced production system“. Based on this point of view, in intelligent manufacturing The research of basic theory, the paper puts forward a model of intelligent manufacturing s
