英文原文manuf The development of modern acturing industry Dies Die in machinery, electronics, light industry, automobile, textile, aviation, aerospace and other industrial areas, has increasingly become the most widely used, the major industrialized production technology and equipment, it incurred these industrial fields in 60% 90% product parts, the machining parts and components production. Die industry is the basis of the national economy industries, is a universally recognized key industries, is large investment and the slow return of labor-intensive and technology-intensive industries. The high-tech industry in the world die has been described as a point Tiecheng gold industry. Therefore, all of the advanced industrial countries Die industrial development a priority. As a basic industry, mold quality, accuracy and lifetime, cost, delivery services and manufacturing cycle for other industries as well as scientific research and development will not only promote the role, but also by other related industries, and science and technology constraints. Today, the die is the quality of products, Die is the economic benefit concept, has been more and more people will recognize, to accept. Die technology development directly related to product quality, production efficiency Rates, updating and development. Modern Die technological development, to depend on the mold level of standardization, quality mold materials research, design and manufacture of advanced technology, equipment and machine tools for the production technology management. One CAD / CAM technology in the production of mold, no doubt plays an important role. It was considered modern technology Die And the core of an important direction of development. 1 CAD / CAM industry development trends 21 die manufacturing industries is the basic characteristic of highly integrated, intelligent, flexible and networking. Pursue the goal is to improve the product quality and production efficiency, shortening design and manufacturing cycles, reduce production costs, maximize the mold manufacturing contingency capacity to meet user needs. Specific performance for the following seven characteristics. (1) Integration Technology Modern mold design and manufacturing system will not only should be emphasized that the integration of information should also be stressed that technology, and management integration. Die manufacturing system in the development, stressed the multi-integration concept, that is, information integration, intelligent integration, integrated string parallel mechanisms and personnel integration, manufacturing system more suitable for future needs. (2) intelligent technology Application of artificial intelligence technology to achieve all aspects of the product life-cycle of intelligent, and all aspects of the production process to achieve the intelligent, intelligent and die equipment, but also bringing people and systems integration and in which intelligent people into full play. (3) the application of network technology Network technology including hardware and software to achieve integration. Various communication protocol agreement and manufacturing automation, information communication interface, system operation control strategy, and so is the realization of various manufacturing systems automation foundation. At present there has been cross-border via the Internet to achieve successful examples of mold design. The application of network technology for the realization of Chinas Die agile manufacturing enterprises and dynamic alliance laid a technological basis. (4) Multi-function integrated multidisciplinary product design technology Future product development design not only uses mechanical scientific theories and knowledge, but also use electromagnetism, optics, control theory, and so on, even taking into account the economic, psychological, environmental, health and social, and other relevant factors. Product development to conduct multi-objective optimization of the performance of the entire design, mold products in pursuit of dynamic and static characteristics, efficiency, accuracy, service life, reliability, manufacturing cost and the best combination of the manufacturing cycle. (5) virtual reality and multimedia technology applications Virtual reality VR (Virtual Reality) is a man-made computer environment, in this kind of an environment people are realistic feel, and stressed that the involvement of people with the operation. VR technology in the 21st century the entire manufacturing will have a wide range of applications, can be used for training, manufacturing system simulation, simulation-based design and manufacturing production, integrated design and manufacturing to achieve the integrated design. The United States was in 1999 through the use VR technology successfully rehabilitated Kazakhstan stroke Space Telescope. Multimedia technology uses a variety of media to store, handle a variety of information into text, voice, images into one, giving the impression that the truth Real flu. (6) Application of Reverse Technology Conventional die design usually have to design products based on the information. These design information through engineering drawings or models to express, and then develop processing technology planning, the eventual adoption of Tooling / mold and equipment manufactured products. But in many cases, some products does not come from the design concept, but originated in some other products or in kind, only to physical model or prototype products, but not under the conditions of product design for the mold design and manufacturing to produce products . Through this kind of measurement, and then use physical measurements of CAD geometry model of re-structure. This process is the reverse engineering RE (Reverse Engineer-ing). Once established CAD geometry of the model, this can be based on the geometric digital model for many of the follow-up operation, such as physical changes to the CAD model, the redesigned parts, finite element analysis, error analysis, numerical control (NC) machining instructions Generation and die design and manufacturing. (7) Rapid Prototyping Manufacturing Technology Rapid Prototyping Manufacturing Technology RPM (Rapid PrototypingManufacturing) based on the principle of manufacturing, create rapid prototype, but with the geometric complexity of the parts has nothing to do, particularly in the complex surfaces of products manufactured in the shape better demonstrate its superiority. It not only can quickly create prototypes for design evaluation, the assembly of the school seizure, functional experiments. They can also shape through reproduction, rapid economic create products to Die (such as the manufacture of electrodes for EDM processing, as a die-casting mold disappear, etc.), thereby avoiding the time-consuming traditional mold manufacturing costs and consumption of NC machining, thus RPM Die Manufacturing Technology in playing an important role. 2 domestic CAD / CAM application status The current domestic industry mold the basic situation is that, with a light industry and the rapid development of automobile manufacturing, mold design and manufacturing increasingly wide attention by the people, has become an industry. However, our lack of technical personnel die industry, the existence of small, low accuracy, the manufacturing cycle length, short life, in short supply situation. Some large, sophisticated, complex mold also was not able to produce, need to spend millions each year, tens of millions of dollars from foreign imports, which restricts the development of the industry, in our country it is imperative to vigorously develop the tooling industry. In order to improve the design of die enterprise level and processing capacity. China to the National Association of Die Die Die industry enterprises recommended for use in the CAD / CAM system. Mold design and the use of the processing of CAD / CAM systems, does not require system is enormous, but certain aspects of higher demand, such as surface modeling, 3-axis NC machining, etc. Some foreign CAD / CAM system, despite a strong three-dimensional surface modeling capabilities, a powerful structural finite element branch capabilities, powerful computer-aided manufacturing capabilities, product data management capabilities, but is expensive, generally it is difficult for enterprises to pay. While domestic excellent CAD / CAM system rarely, only a handful of applications for mold industry, such as China is the CAD / CAM system, it has an autonomous copyright and low prices. Some large mold for domestic enterprises, their CAD / CAM application of stays from abroad in the purchase of advanced CAD / CAM systems and equipment, but in its second development was carried out on fewer, low utilization of resources; some of the domestic Die small enterprises, their CAD / CAM applications rarely, some only remain in the computer graphics instead of solid plate. It is necessary to improve the domestic enterprises die of CAD / CAM application status, so that they truly rapid and accurate response of the market, and manufacture of high quality products Die low cost, that is, to achieve the purpose of agile manufacturing. 3 Die industrial organizational structure of the status quo industry Now, Chinas mold production enterprises can be divided into four categories: professional mold plant, specializing in the production of mold, for the product works or Die Plant Workshop to supply the necessary products plants die as the main tasks of the mold-funded enterprises branch, its organizational model and professional mold plant similar to the small and the main township enterprises die, and is similar to professional mold factory. A second category of which the largest number, about mold production output of 70 percent or more. Chinas mold industry decentralized management structure, there are currently 19 major industry sectors manufacturing mold, the use of mold, but no unified management of the sector. On China Die Industry Association to co-ordinate the planning, concentrated on attacking the problem, cross-sectoral and inter-departmental management difficulties many. Die suitable for the production of small and medium enterprises, and technological transformation of Chinas large and medium-sized enterprises to tilt investment, small and medium enterprises Die investment can not be guaranteed. Plant products including die shop and the factory, and after technical transformation can not recover their investment quickly, and many die after the heavily indebted technological upgrading of enterprises, affecting its development. Although most products plants die shop and the plant strong technical force, equipment conditions are better, the die level of production higher, but low capacity utilization. My mold with its value price for a long time uncoordinated, resulting in mold industry own small economic benefits, social benefits, the phenomenon. Die Stem Die Stem is better than the standard parts, stem dry is better than standard parts with pieces of mold production, the production of dry zone Mold processed products as serious anomalies exist, have greatly dampened Die enterprises (including Die workshop and Plant) to their initiative. This is also mold industry talent留不住, youth and technical personnel, youth workers to the cause of science and technology. 4 Die dynamic coalition-building industry Mold Industrial Organization from the industrial structure of the status quo can be seen in the current domestic enterprises Die most fragmented industry, due to the various resource constraints make the development of new products and long hours, the user needs unresponsive, to the detriment of enterprises to participate in market competition. To enhance their market competitiveness, played the entire industry advantages, die industry it is necessary to establish dynamic alliance. The idea is dynamic alliance will develop a new product with the necessary knowledge and technology of different organizations (companies) to form a temporary alliances to jointly cope with the challenges of the market, joint participation in international competition. The establishment of dynamic alliance can complement insufficient resources and increase the success of the series; mutual compensate for the deficiencies and improve technical development capabilities for strategic and technical means to ensure that all the necessary information; evade research and development risks; pursuit of the spread of technology development and training and to ensure that researchers and technical personnel; enhance the credibility of enterprises, develop and expand the market will be conducive to the diversification and internationalization; evading technology friction. The dynamic alliance members should be on the basis of mutual trust, based on the need for cooperation and problem-solving, and the mutual sharing of information all the partners. Dynamic Alliance members possess their own technological superiority. Technology and revenue sharing, group risk. Trust is the cornerstone of dynamic alliance, both competition and cooperation, forming a virtuous circle. Driving the interest is the participation of members of the League of dynamic driving force, and, the dynamic alliance needed for the operation of a sound legal system, the rules of fair competition, standardize enterprise behavior, and so a good external environment. Die industry dynamic alliance will need the establishment of the technical foundation for these technologies and the previously mentioned foundation for the future development direction of the same mold, which mainly includes five aspects. (1) based technology - advanced manufacturing technology Advanced manufacturing technology is for the purpose of improving overall efficiency, the main man-made, computer-pillar, comprehensive application of information, materials, energy, environmental protection and other high technology and modern management techniques, research and the transformation of traditional role in the manufacturing process throughout the entire life cycle of products all applicable technology for building dynamic alliance with the effective functioning of the lay a solid foundation. (2) Environmental Technology - Network Technology To achieve virtual companies, enterprises need to have communications connectivity, the use of high-speed broadband networks, linking all members effectively. Sharing resources to achieve tele-design and manufacturing. At the same time, we can also use it to establish a
