This paper presents results of research in the area of Computer-Aided Process Planning (CAPP) for discrete part manufacturing. A new approach to generative process planning is described. The delineated concept makes great demands on the modelling of intermediate workpiece states during the manufacturing process. Nevertheless, the approach has already been successfully applied in industrial projects for workpiece families whose modelling requirements are relatively elementary. Recent progress in the area of feature-based modelling, leading to a new generation of CAD-modellers, will allow the investigated approach to be applied to a broader workpiece spectrum in mechanical engineering. This paper presents not only the planning approach itself but relates it to current developments in geometric modelling.
