摘要
提出了一种多岛屿复杂曲面的刀具路径规划算法。利用空间填充曲线分形级数的增加能够填充整个曲面的特点,对Hilbert分形曲线进行改进并结合多岛屿曲面特征进行刀具轨迹规划。生成的刀具轨迹能够较好的避开岛屿且无需抬刀,能够生成一条连续的且能满足加工精度要的刀具轨迹,能够极大缩短刀具路径整体长度。在加工过程中,刀具无多次切入切出现象,切削稳定,能够提高其表面质量,加工质量相对较高。通过实例验证了算法的可行性及有效性。
The tool path planning algorithm of Surfaces with multi-island was presented. Combined with multi Island surface feature,the tool path planning using the improved Hilbert fractal curve. The tool path generation can avoid the islands on the machining surface,and do not appear this kind of phenomenon that lifting tool. It is continuous tool path that can shorten the length of the overall trajectory and meet the machining accuracy .In the process,the tool has no multiple exit cutting and once again into the cutting phenomenon,which can prove the quality and efficiency of machining process. The example demonstrate the proposed method is avoid and feasible.
