摘要
在光栅线轨迹模式下,曲面工件的磁流变抛光需通过五轴联动来实现,基于自研的PKC-600Q磁流变抛光机床运动轴配置的几何模型,给出了由曲面解析式得到的被加工点的方向余弦,并详细推导两个摆动轴角度的计算方法。该方法易于理解,不依赖CAD/CAM软件,便于集成到磁流变抛光专用工艺软件中,同时也可以在曲面工件其他方法加工中参考应用。
Processing a curved surface in magneto-theological finishing （MRF） by raster path, 5-axis machine is necessary. Based on the geometric model of axis distribution in developed PKC-600Q MRF ma- chine, the direction cosine of the finishing point are calculated from the surface expressing, and farther on, with a simple and specific method independent of CAD/CAM software, angles of the two swing axis are al- so calculated from the direction cosine. The method is easy to integrate in self-developed MRF software. Besides MRF, the method is also suitable for other processing of curved surface.
