摘      要：For the designing of cutting-dies is a complex and experience-based process,it is poorly supported by conventional 3D CAD ***,the majority of design activities,including the(re)modeling of those cutting die-components that are directly responsible for performing shaping operations on a sheet-metal stamping part,traditionally still need to be carried-out repetitively,separately,and manually by the *** eliminate some of these drawbacks and upgrade the capabilities of conventional 3D CAD software,this paper proposes a new methodology for the development of a parametric system capable of automatically performing a(re)modeling process of compound washer dies *** presented methodology integrates CATIA V5 built-in modules,including Part Design,Assembly Design and Knowledge Advisor,publication mechanism,and compound cutting die-design *** system developed by this methodology represents an intelligent assembly template composed of two modules GAJA1 and GAJA2,***1 is responsible for the direct input of the die-design problem regarding the shape,dimensions and material of the stamping part,its extraction in the form of geometric features,and the transferring of relevant design parameters and features to the module ***2 interprets the current values for the input parameters and automatically performs the modeling process of cutting die-components,using die-design knowledge and the company s internal design and manufacturing *** results show that this system significantly shortens the modeling-time for cutting the die-components,improves the modeling-quality,and enables the training of inexperienced designers.
