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。

关 键 词:计算机辅助制造  等参数线刀轨  调和映射  区域划分  三角网格曲面

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.
Keywords:computer aided manufacturing(CAM)  iso-parametric tool path,harmonic map,region segment,triangular mesh surface,
