An approach to generate arc spline tool path of triangular mesh surface was proposed.CL(cutter location) points of interference-free line tool path were obtained by intersecting offset surface of triangular mesh surface with a series of parallel drive surfaces of variable path interval,and these points were classified into three categories and the redundant points of each category were removed with the least square fitting separately,then the fitting precision of CL points was revised by mapping tool path deviation into fitting deviation.After transition process of line-arc tool path,the developed arc spline tool path holds G1 continuity and high precision.Experimental result indicates that the presented approach is effective.
