Development of expert systems for forging processes

Abstract The authors have been working on the development of two expert systems for use in the Forging Department of their firm. The first is the previously developed “YOURS” automatic design system for forging dies, which can reduce the design costs and shorten the development time of new parts. The second system, which we call “FORDIA,” has been developed as a means of diagnosing the causes of forging defects. This system employs an AI technique (the “Bayesian Network”) and depicts both empirical knowledge and theoretical knowledge obtained by the FEM analyses.
