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.

4 conclusion and further work
The application of computer aided design tools in the application of metal forming, save a lot of time and money. Due to complex parts the complexity 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 form 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 complex 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 computer to execute geometry calculation and automatic get design results. It provides a very flexible design environment, users can complete mastery of even complex 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.
