Abstract |
On the basis of analyzing characteristics of stamping die products and their designing process, a design method combining rough set theory and case-based reasoning is proposed. Firstly, the paper introduces the information system of case-based reasoning based on rough set. Then, the paper presents storage strategies of stamping die case library and implementing examples. In order to retrieve cases similar to the case being studied in the library, the Nearest-Neighbors-based similarity measurement method is used. Thirdly, the paper gives an approach for reducing attributes and calculating weights to raise the accuracy and efficiency of case retrieval. At last, writers apply the method to develop a stamping die CAD system prototype. |
