The Development of a Die Sinking System by "Skewed Cube Modeler"

Abstract

This paper describes development of the CAD/CAM system based on the "skewed cube modeler" named DIMOS. To handle complicated 3-D die shapes with CAD/CAM systems, it is necessary to develop the new modeling method suitable for 3-D die shapes. The DIMOS method, based on the decomposition method, is represented by "shell", "seed" and "split point", and has advanced capabilities to treat both sculptured surfaces and solid model at the same time. The CAD/CAM system using the die manufacturing model based on DIMOS method generate tool path from 3-D die shapes with high accuracy and computing speed.
