Feature elimination method for computer-aided forging process planning is reported in this paper. The authors think that forming is the procedure adding features to a raw material and process planning is the procedure eliminating features from a product. This procedure is done only in planner,s mind. The authors attempt to implement this feature eliminating procedure for forging sequence design on computers. Eliminating order is determined by using characteristic vector of 'pair matrix.' Elements of 'pair matrix', called 'pair elements', are calculated from the possibility that one of features is formed earlier than the another. Each possibility is compiled from a forge expert's 'know-how' by comparing each two kinds of feature. Possibility is computed by fuzzy inference if it cannot be determined from only kind of a pair of features, but also dimensions. We call this case 'dimension problem'. The authors apply the above methodology on manufacturing sequence design of axis-symmetric forging products, and investigate data of pair matrix and reasoning rule for dimension problem by interview with forge experts.
