| 摘 要： | 提出一种三角网格曲面等参数线刀轨生成算法。采用调和映射的方法对三角网格曲面进行参数化，给出了四种等参数线刀轨规划方式;根据网格模型、投影网格和参数网格之间的对应关系，由残留高度确定参数网格中的x或r参数线;在此基础上，采用“区域划分”的方法快速生成了无干涉、无冗余数据的网格曲面等参数线行切和环切刀轨。实验结果表明该算法是可行和有效的。

| Abstract: | An algorithm for iso-parametric tool path generation for triangular mesh surface machining was proposed.Mesh surface was parametrized firstly by harmonic map method,and four types of iso-parametric tool path planning were put forward,then x or r parametric lines were determined in parametric mesh by the corresponding relations of mesh surface,projected mesh and parametric mesh.Based on these, iso-parametric tool paths of free-interference and no redundant points were generated rapidly by region segment method.Experimental results indicate that the proposed algorithm is feasible and effective. |
