Intelligent system technology can improve the efficiency of the stamping process planning. 2 system frame and the frame Intelligent system key technology is built and application of information model making. This product information model, including three stages: a kind of the model, based on geometric model based on features based on intelligence, the model. Based on geometric model describing the geometric topology information parts. Because parts of data message cannot be fully described, data separation level is too low, geometric model was characteristic model replaced. This information model includes a set of geometric entities. Rely on this model, the engineering semantic model with design of related functions many can be realized. Along with the development of artificial intelligence, the intelligent model begins to be used. Professional knowledge, design process of knowledge, and relevant knowledge are included 9 in the knowledge model [9, 10]. Intelligent model support expression and transfer of useful information. This paper mainly summarizes a stamping process planning of intelligent system. This intelligent system for product definition effective and plete. It has the advantages of different geometrical model and can satisfy the geometric designs and reasoning process. Objectoriented technology is applied to integrate all kinds of knowledge. This integrated knowledge system model can be Shared and used in intelligent design and product information munication. Figure 1 shows the stamping process planning intelligent system frame This about stamping mould process planning of intelligent system frame has been designed. The ponents of the structure design, including a graphical user interface, an application system, design resources, knowledge tool, mixed reasoning mechanism, basic model. In this architecture knowledge model have different classification. Knowledge model from the design resource to extract useful information, support knowledge acquisition and knowledge expression program. This model is useful information transferred to knowledge. Comprising CAD software support. Design results as a 3D model, pictures and database is stored in the repository, it in different parts of the knowledge base is very important knowledge transfer. 3 implementation method and application stamping feasibility of intelligent model Intelligent system for stamping workpiece quality, cost, die life is evaluated. This evaluation based on mature intelligent model. This model has integrated rule library, parts information and conclusion library. Coefficient of knowledge rule reasoning in knowledge according to that. Stamping forming feasibility can from a database of information and related coefficient parts launch. In the design process of the extension of the new conclusion preserved in conclusion library. Model of intelligent reasoning process and parts specification limits range pared with the technological parameters. This specification Including input/output radius, aperture, orifice plate, hole s, chamfer, trough s. Results to confirm whether accord with the shape of mould parts processing tools. Intelligent reasoning is used in the automatic and interactive way. It39。t satisfy the users of all the requirements. Depended on the knowledge model data structures, by moving point and change steps, increase steps and deletes empty empty the purpose can be realized step. We can pass the data processing steps to revise the ribbon of the layout design results. Step change can work through exchange of coding to realize two positions, work step increase or decrease can insert or removed by the operation to plete. Code When we want to move some point, we can from the first step to the last step transfer list is points. Figure 7. Shows is the ribbon automatic placement design result [11]. Figure 7: ribbon automatic placement design result sure stamping center and force calculation of intelligent model. Press center design model establishment is the purpose of the group operates [11] together. Mould tool center and stamping center39。s point of view is calculated. 5.
