Construction of PC-based expert system for cold forging process design

Abstract Cold forging process design is a field where the theory has not been established until present, and it depends on skilled designers with long time experience and intuition. Consequently, it is difficult for designers with shallow experience to cope, since process design needs time and cost. Thus, computer-based expert system for cold forging process design targeted to beginners has been developed in this study. In this system, a case base is used as the knowledge base and the fuzzy pattern matching is used as a reasoning theory. Due to the case base, composed of geometric data, been designed by the human expert, it has uncertain factors such as the subjectivity of the human experts. Therefore, the fuzzy pattern matching can be applied to generate appropriate design results from little and uncertain knowledge included in the case base.
