【正文】 These point name is k1, k2,..., dij kn. Here Kj ki and is the smallest distance between. Matrix critical value is S. If dij S, ki and kj Can39。t draw in the same steps. This kind of situation is intelligent model of the conflict between two points. Development of the intelligent model interference point ChongTuDian aim was to determine the existence. This matrix is a system matrix. In order to make the design process is more convenient, can put the matrix of half part element zeros. 13 Here, mu ij correlation coefficient, which it says is for every to point between different relations. If there is a contradiction between two points, one of them is to be moved to the next step. In every step of ChongTuDian disappear until repeat this step. Finally matrix M bee empty matrix. The shingles layout of trace process The layout of the shingles son two of handling knowledge model: change results and create part graphic layout. Automatic design model from ribbon layout draw result is staple. They may can39。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 consistent is very important, only as stamping tools can together the normal work. Press center from the knowledge model calculation of every contour position in conclusion. Design is to get the first part of the tools work area. CAD platform of parts provided parts of graphic outline the rectangle. Rely on stamping center and the relationship between the rectangular can generate work area. Because of the result of unbalanced force is the possibility, it also offers stamping center regeneration into. Regeneration by humanmachine interface into steps to plete. Software Figure 8 shows as the posite modulus stiletto mechanic for design of area results. Stored in the repository includes every type of mould tool parts blanking, waste removal, etc. Different situations force calculation method is different. By force equations is obtained knowledge rules, the reasoning of the library. First, processing power and cutting force is based on parts of the contour length and knowledge base knowledge rules get. Then, through the design results, can get harmony parts from force, resistance and push a force. Total force the guide according to knowledge step by step calculation. Figure 8: posite modulus punching machine work area. 4 conclusion and further work 14 The application of puter aided design tools in the application of metal forming, save a lot of time and money. Due to plex parts the plexity of stamping process design to develop a system of automatic generation process step is very important. This study developed an integrated CAD system, this system developed a process planning system makes for an irregular parts in high speed into precision processing can be realized. The system has the features: 1. In the design process changing data in different ways to save, including digital for m and picture form. Users in the design process can freely use them as reference. 2. Check the model check processing feasibility, the feasibility of can also pressing for plex parts stamping process planning with some Suggestions. 3. Arrangement module generating optimal arrangement graph the biggest arrived on the material utilization. The product cost reduction depends on the strip layout optimization calculation. Not only the best planning and every reasonable planning are stored in a knowledge base. Users can choose any one as their final design results. 4. Ribbon arrangement module automated process plan. According to the requirements of customers, the results can be ribbons in the strip layout design process of any period modification. In process planning of this system in assist designer will be a useful tool. It will be enough flexibility allows designers creative, at the same time use the puter to execute geometry calculation and automatic get design results. It provides a very flexible design environment, users can plete mastery of even plex parts stamping process planning and design. This system has a graphical interface, user can in the design process of design parameters geometrial change. Further work will focus on the strip layout optimization efficiency improvement and optimization will reduce though. For the strip layout planning, more design scheme types should be added to the knowledge model. According to the result of stamping process planning, stamping mould design applications will also work in further by research
