With the development of economy and the rapid development of science and technology, the machinery manufacturing industry is facing higher and newer requirements: combining with computer technology and information technology to achieve the goals of intelligence, automation, high yield, high efficiency, low energy consumption and no pollution. This paper introduces advanced manufacturing technology from several aspects, and points out the development direction of machinery manufacturing industry. Keywords advanced manufacturing technology As a traditional field, mechanical manufacturing industry has accumulated a lot of theoretical and practical experience after years of development. However, with the development of society, people's living standards are improving day by day, and the personalized needs in all aspects are becoming stronger and stronger. The machinery manufacturing industry, which has penetrated into all walks of life and become a basic industry, is facing severe challenges. The concept of advanced manufacturing technology points out the direction for the development of machinery manufacturing industry. Although there is no clear definition of this term, it is generally believed that advanced manufacturing technology is the result of traditional manufacturing technology constantly absorbing machinery, electronics, information, materials, energy and modern management, which is comprehensively applied to the whole manufacturing process of product design, manufacturing, testing, management, sales, use and service, achieving high quality, high efficiency, low consumption, clean and flexible production and achieving ideal technical and economic effects. It has the following characteristics: 1. The change from technology-centered to people-centered makes the development of technology more in line with the needs of human society. 2. From emphasizing specialized division of labor to fuzzy division of labor, an expert can do many things to give full play to the wisdom of workers. 3. Change from pyramid-like multi-layer management structure to flat network structure, reducing levels and intermediate links. 4. Change from the traditional sequential working mode to the parallel working mode, shorten the working period and improve the working quality. 5. From the fixed organizational form of dividing departments according to functions to the dynamic and self-managed group work. 6. The development trend of mechanical manufacturing technology can be summarized as: (1) mechanical manufacturing automation. (2) Precision engineering. (3) The improvement of traditional processing methods and the development of non-traditional processing methods. The automation technology is discussed and prospected below. Mechanical manufacturing automation technology has always been the most active research field in mechanical manufacturing. It is also the main means for manufacturing enterprises to improve productivity and win market competition. Since the emergence of mechanical manufacturing automation technology in the 1920s, it has gone through three stages: rigid automation, flexible automation and comprehensive automation. Integrated automation is usually associated with concepts such as computer aided manufacturing and computer integrated manufacturing. It is the synthesis of manufacturing technology, control technology, modern management technology and information technology, aiming at comprehensively improving the labor productivity of manufacturing enterprises and the response speed to the market. 1. Integrated Computer Integrated Manufacturing (CIMS) is considered as the main mode of production for manufacturing enterprises in 2 1 century. CIMS consists of several interrelated parts (subsystems), which can usually be divided into five parts: 1. Engineering information subsystem includes computer aided design (CAD), computer aided engineering analysis (CAE), computer aided process planning (CAPP), computer aided tooling design (CATD) and numerical control programming (NCP). 2. Management information subsystem includes operation management, production management, material management, personnel management and financial management. 3. Manufacturing automation subsystem (MAS) includes various automation equipment and systems such as computer numerical control (CNC), machining center (MC), flexible manufacturing unit (FMS), industrial Robot (Robot) and automatic assembly (AA). 4. The quality information subsystem includes computer-aided detection (CAI), computer-aided testing (CAT), computer-aided quality control (CAQC), coordinate measuring machine (CMM) and so on. 5. Computer network and database subsystem (network &; DB) It is a supporting system, which is used to link the above subsystems and realize the integration of each subsystem. Second, intelligent intelligent manufacturing system can be understood as a man-machine integrated intelligent system composed of intelligent machinery and human experts, which can carry out intelligent activities such as analysis, reasoning, judgment, conception and decision-making in the manufacturing process. In the intelligent system, "intelligence" is mainly reflected in the excellent "soft" characteristics (adaptability and friendliness) of the system. In the process of design and manufacture, modular method is adopted to make it more flexible; For people, intelligent manufacturing emphasizes safety and friendliness; For the environment, it is required to be pollution-free, save energy and fully recycle resources; For society, we advocate reasonable cooperation and competition. Three, agile manufacturing is based on competitiveness and reputation, choose partners to form a virtual company, division of labor and cooperation, for the same goal * * * efforts to improve the overall competitiveness, rapid response to user needs, in order to meet user needs. In order to realize rapid adaptability, the establishment of virtual enterprise is the key technology, and its core is virtual manufacturing technology, that is, agile manufacturing is based on virtual manufacturing technology. Agile manufacturing is the only way for modern integrated manufacturing system to develop from information integration to enterprise integration. Its development level represents the development level of modern integrated manufacturing system and is the development direction of modern integrated manufacturing system. The technical basis of agile manufacturing includes: 1. Large-scale communication infrastructure, which requires the establishment of factory information networks and instant information systems nationwide. 2. Flexible modular product design method. 3. Highly flexible, modular and extensible manufacturing system. 4. Design and manufacture the production mode for the order. 5. Task-based organization and management. 6. Employment relationship based on trust. 4. Virtualization The concept of "virtual manufacturing" was put forward in the early 1990s. Based on system modeling and computer simulation technology, virtual manufacturing integrates modern manufacturing technology, computer graphics, information technology, concurrent engineering, artificial intelligence, multimedia technology and other high and new technologies, and is a comprehensive system technology formed by multidisciplinary knowledge. Virtual manufacturing uses information technology and simulation computer technology to comprehensively simulate people, things, information and manufacturing process in real manufacturing activities, so as to find possible problems in manufacturing and take preventive measures before actual production of products, realize one-time manufacturing success of products, reduce costs, shorten product development cycle and enhance product competitiveness. 5. Cleaner production refers to the continuous application of comprehensive preventive environmental strategies in production processes and products to reduce the risks to human beings and the environment. The two basic goals of cleaner production are comprehensive utilization of resources and environmental protection. As far as the production process is concerned, cleaner production needs to permeate the whole process from the input of raw materials to the output of finished products, including saving raw materials and energy, replacing toxic raw materials and scarce resources, using secondary energy and renewable resources, improving processes and equipment, and reducing the quantity and toxicity of all emissions before leaving the production process. As far as products are concerned, cleaner production covers all stages of the whole product life cycle, from the extraction of raw materials to the final treatment of products, including product design, production, packaging, transportation, circulation, sales and scrapping. , so as to make rational use of resources and minimize the adverse impact on human beings and the environment. To sum up, the development direction of machinery manufacturing industry is to organically combine traditional manufacturing technology with modern information technology, management technology, automation technology and system engineering technology, and organically integrate and optimize the organization, operation, management and technology of enterprise products in the whole life cycle through computer technology, so as to realize the informationization, intelligence and integration optimization of enterprise products in the whole life cycle, achieve the purpose of fast product listing, good service, excellent quality and low cost, and further improve the flexibility and robustness of enterprises.
