With the rapid development of CAD/CAM system and CG technology, design and manufacturing of complicated shape became possible. Usually machine tools with five axes are used for processing of this complicated shape. Generally increasing the number of axis will increase the DOF (degree of freedom) and flexibility of machine tool. However, with the number of axis increases, the calculation of tool path becomes complicated. On the other hand, with the CAD model became more and more complicated, it is difficult and time consuming to machine such models. In this research, we aim to improve the rough machining efficiency for freeform surface machining, and a turning center is used as the machine tool. In this paper, a rough machining tool path generation method based on multi-resolution mesh is proposed. It uses low-resolution models with simple shapes in the rough machining process to rapidly remove the redundant materials. The efficiency of this proposed method is proved by simulation result. |
