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。s researchers are also studying stamping process and punch die special system. [6]. The focus of their study in deposed smaller bridge waste shape coding and recognition technology. [7] in Shanghai stamping mould and tools institute of technology researchers also 8 developed progressive die CAD/CAM system.
