To realize the reversal design and manufacture of product based on the triangular Bézier surface modeling technology,a generating algorithm of contour-parallel tool-path for triangular Bézier surface model was proposed.Through optimizing R*-tree's construction process,dynamic index of triangular Bézier surface model was established.The triangular Bézier surface patches in instant processing region were acquired based on proposed index,and interference-free cutter location points were iteratively calculated ...
