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 location points were ordered by using the minimum spanning tree algorithm, and which is proved that the algorithm can improve the efficiency of NC tool path generation and process precision effectively.
