In designing a holder part of a large stamping die, designers must consider not only the functional property of the holder, but also its manufacturability. The holder part is produced by cutting and engraving table, wall, slot and pocket features into the raw cast shape. Since designers do not always have enough knowledge about the manufacturing method, they sometimes design a part with some unmanufacturable features. The author develops a new system for suggesting a design modification method to eliminate such unmanufacturable ones. This system automatically determines some optimum positions of a cutter for completely machining the unmanufacturable feature. Such cutters in the optimum positions have interferences with the holder part. Our system visualizes the interference volume between the cutter and the holder part. The designer can determine the design modification method of the holder part based on the interference volume.
