摘要 采用多轴联动计算机数字控制系统的砂带磨削设备能够高效率加工具有复杂型面的零件。针对该类砂带磨削设备,提出了自由曲面上的等参路径规划算法和等间距截面路径规划算法。路径规划算法中的相邻刀触点的计算是根据磨具在进给方向的有效投影位置确定。等间距路径规划算法用最小二乘法来获取较优的截面法向。为了提高路径规划设计效率,减少试验以提高经济效益,开发出基于线性磨削模型的砂带磨削几何仿真程序。汽轮机叶片加工的试验结果表明该算法能够很好地应用于复杂型面的刀具路径规划设计。 Belt grinding machine with multi-axis computer number control(CNC) system can effectively process parts with complex moulding surfaces.In this paper,iso-parametric and iso-planar tool path planning strategies customized for this kind of machine are proposed.The tool path generation methods are designed based on the analysis of the belt grinding process.By using least square method,optimized cross section normal is computed in the iso-planar method.To improve the design efficiency of path planning,reduce experiments and increase economical benefit,the geometric simulation program based on linear grinding model is developed.Experiment on a turbine blade profile shows that the proposed algorithms work satisfyingly.
