Intelligent Mold Cad System

In this thesis, an intelligent CAD system of die is discussed, especially about the intelligent design of the die structure. In the thesis, the author proposes the frame of the die intelligent CAD system. CBR (Case-Based Reasoning) is applied to solve the problem of die structure design. This is different from the traditional design. In the thesis, the author researches how to express the die case, organize the case base, and retrieve the case. At (he key nearest algorithm system, fuzzy reasoning is used to retrieve the case according to the similarity between the die structure cases. The system also provide a strategy to reuse the retrieved case and make the system can study by itself.According to the algorithm model proposed by the author, a system software is developed on PC PIII. The software is programmed based on UG, and uses UG/OPEN API...
