| Abstract: | In the pressent paper, a new CAPP information model based on the characteristic code, using the group technology , is proposed for the types of axisymmetric drawing cups. First, the characteristics of the axisymmctric drawing cups are discussed, and the information on these types of parts is investigated. Then, a system model of CAPP based on the characteristic code and the relevant techniques are analyzed in detail. The proposed method not only has the advantage of automatic process design and the group technology for these specific parts, but also has the advantage of group design and reuse of punches and dies. |
