The various approaches proposed to provide communication between CAD systems and process planning systems share the major problem that, due to geometric interactions among features, there may be several equally valid sets of manufacturable features describing the same part, and different sets of features may differ in their manufacturability. Thus, to produce a good process plan-or, in some cases, any plan at ll-it may be necessary to interpret the part as a different set of features than the one initially obtained from the CAD model. This is addressed using an algebra of features. Given a set of features describing a machinable part, other equally valid interpretations of the part can be produced by performing operations in the algebra. This will enable automated process planning systems to examine these interpretations in order to see which one is most appropriate for use in manufacturing. The feature algebra has been implemented for a restricted domain and integrated with the Protosolid solid modeling system and the EFHA process planning system.
