Intelligent stamping process planning system research Abstract: this paper to build a intelligent stamping process design knowledge based system gives a brief introduction. Study the system framework of model, and knowledge reasoning model are introduced. For some key technologies such as the feasibility of stamping process and exhaust kind of best algorithm, intelligent zone layout and internal force calculation is studied. This system can improve process planning efficiency. 36419

introduction
Stamping process planning is one of the core punching product development project. It is the metal molding application an important component part of it and the production quality, cost, productivity and tool life have direct influence. The rapid development of modern manufacturing for stamping put forward higher request, especially in stamping process. For many years, the related research has the environment in innovation to strengthen the integration and process planning study intelligentize degree. In recent years, through the production of metal forming intelligent design system, automation technology, the whole and the process planning principles. Intelligent process planning method can effectively improve the design efficiency and quality, innovative design ability.
[1]. For cold forging sequence of designing and developing a kind of expert system based on PC, this system based on practical considerations plasticity theory and the rules. At the Ohio state university, a called FORMEX rules system is Altan and his colleagues write multistage cold forging process planning and programming language. [2]. It depends on a cold forging parts of various shapes widely classification. [3] implement knowledge based cold forming sequence design system, adopting the design rule sure to establish a feasible sequence, then using finite element analysis optimization this sequence. A knowledge based mold design automation system is Cheok and his colleagues carefully designed. [4] in the national university of Singapore. Some parts representation techniques, stamping parts recognition and mould constitute also exists in this work. In China, huazhong university of science and technology researchers also developed based on knowledge system for small metal parts stamping progressive die program packages. [5]. Use features, users can under 3D architecture design products. In manually set arrangement, user can use interactive command to development zones outfit layout design. From Liverpool university industrial research department's researchers are also studying stamping process and punch die special system. [6]. The focus of their study in decomposed smaller bridge waste shape coding and recognition technology. [7] in Shanghai stamping mould and tools institute of technology researchers also developed progressive die CAD/CAM system. They study the system depend on special relevant data to describe the workpiece and mould structure.
The findings of the research work purpose is to promote the development of metal forming process. From metal intelligence review and analysis of the forming of intelligent design, use the theory and method to study the stamping process planning steps. In this paper introduces applied in stamping process planning of intelligent system. This intelligent system in dealing with some complex design problem is a powerful tool. By special knowledge construction intelligent systems can use an interactive way help user to solve all kinds of problems or questions. [8]. Intelligent system is a computer system, it tried to represent human knowledge and professional knowledge, and to a practical and effective way to provide fast, convenient and knowledge. Intelligent system can accomplish generally require experts to complete tasks. It can automatic real-time use existing professional knowledge, and explain its reasoning process. Stamping process planning is a rich knowledge of the complex design process. Integration in the stamping process planning and design of the key techniques of intelligent system is of vital importance. The use of intelligence theory stamping process planning intelligent systems have been proffered. Some key technologies, such as integrated product knowledge modeling and strategic planning comprehensive stamping process was studied. In stamping design including all kinds of knowledge, such as domain knowledge, multitasking knowledge, non-standard knowledge. Each kind of knowledge all need to be integrated into the system. Stamping mould that is the core of stamping process. Must consider the various factors, such as geometry, technical requirements, material properties and stamping feasibility, working procedures arrangement, the structure of mould tool. Stamping process planning is a kind of creative program based on experts' knowledge. Intelligent system technology can improve the efficiency of the stamping process planning. 智能冲压工艺规划系统英文文献和中文翻译:http://www.youerw.com/fanyi/lunwen_34861.html
