| Abstract: | s:An algorithm for finding out automatically the laser_machining pathway for workpiece bound for 3_D laser edge_cutting is given. By using line segments to approximate a curve and small triangles to approximate curved surface to calculate the normal line, the attitude of laser head during machining is calculated based on the relationship between the laser head and normal line, thus 3_D laser edge_cutting is achieved. |
