【正文】 s purpose is to study the feasibility of pressing the product. Intelligent reasoning based on the key is to determine the thickness and the correlation coefficient parts processing limit. Figure 2 shows the feasibility of the model for product flow chart. 10 Figure 2 shows the feasibility of the model for product flow chart. Knowledge rules and design results stored in the database of mechanical reasoning. Parts in knowledge model shape can modify. The decision by the knowledge model stamping process planning is very important step, it also provides to choose a single step process tool or posite tools or a method of improvement tools. All sorts of different domain knowledge, experience and expertise are kept in the process planning of professional system. Based on the development of knowledge base is the mon principle rules expression. The purpose of this step is to integrate professional experience and parts shape based on optimization algorithm of intelligent strip layout model In order to achieve higher material utilization, blank knowledge model was established, the results are stored in knowledge base established basis other modules. In the knowledge base there are four arrangement type: Arranged layout pattern determined With an array of Washington relative pattern Secondranking arranged layout mode two With two secondranking arranged layout relative mode The purpose of establishing the knowledge model is to improve the material utilization. The restrictions by knowledge can provide human experts to choose from. This knowledge model control over the whole arrangement design process. Figure 3 shows the layout rating system structure The first kind of mode selection function is roughly calculated the numerical and working area general outline. This model provides the original parameters. All the information is roughly value resulting from them, no matter the figures are outlined draw or selected. The second mode used to determine the layout type, Angle range, layout size and strip the width. The third kind of mode applied optimization algorithm. Design results include material utilization, material width and every step clearance are kept in this mode, the different layout drawing also generate. In the fourth mode can modify layout results. Eventually parameters include clearance, material each step of grid, and the width, the ability to switch. When the parameters change, layout plans can be updated. 11 This knowledge is the main purpose of the algorithm to optimize the layout planning. This algorithm six steps. 1. The most suitable around in graphics rectangular first generation. The original copy and the distance between the approach is included in the . Figure 4 shows the algorithm. 2. The value of the two ring is among a putation. The two ring is deposed into line and arc units. The distance between each element needs to pensation. And then you can find the shortest distance. 3. The minimum value and calculated the value of the required the difference between is error. When the error less than value, arrangement planning can be pleted. In addition, graphic layout to follow the direction of the view movement. Graph 4: arrangement algorithm. A primitive Angle graphics. B rotation Angle of graphics after 4.
