三角网格细分曲面数控加工刀轨快速生成算

提出了一种基于三角网格细分曲面模型的刀轨生成算法,建立三角网格细分曲面模型的空间聚类索引结构,基于该结构实现网格模型与刀轨截面快速、精确求交获取刀触点集,并根据刀触点对应曲面位置处的微分几何性质确定刀位点,采用最小生成树算法对刀位点集排序生成刀轨.实例证明,该算法可有效提高复杂曲面模型的刀轨生成效率及精度.

of NC Tool Path Generation for Triangular Meshing Subdivision Surface

An algorithm of NC tool path generation for triangular meshing subdivision surface was proposed,which included three steps: first,the tool touching points were obtained through computing the intersection between the meshing model and the section based on the spatial index structure of triangular mesh subdivision surface;second,the cutter location points were generated according to the geometric properties on differential calculus of surface position corresponding to tool touching points;third,the cutter loc...
