| Summary: | 碩士 === 臺灣大學 === 機械工程學研究所 === 95 === In this study, voxel was used to represent the minimum displaying unit. This investing action emphasize on the use of adaptive octree data structure for developing manufactured model. APT (Automatically Programmed Tool) endmill was used to represent various cutting tool geometries, and implicit functions were used to check whether the voxel is deleted or not. The proposed algorithms were both used for endmill cutting of 3-axis machining. Marching cube was used to pursue accurately displaying. Developing a reliable 3-axis NC simulation from solid models can give the proof of correctness for the cutting tool path, and the model appearance after cutting can be rendered. If users use endmill increment movement, it can achieve real-time animation for checking whether the manufactured model is over-cut or surplus.
