Reduction of calculation time of tool path generation for complex 3D models is an important issue in development of CAM applications. In this study, cutting point dependent progressive mesh is applied for the models which are represented by meshes. This method maintaines history of symplification of the 3D model with hierarchical structure. 3D model can be refined and simplified by using the cutting point dependent progressive mesh. Therefore, the tool path is safely generated by reducing the number of meshes appropriately. Moreover, calculation time can be reduced. In this paper, a tool path is generated by using cutting point dependent progressive mesh, and the calculation time and the result of tool path generation are evaluated.
