Abstract

PURPOSE:To improve the yield of a material by cutting sectorial pieces having the shape of a doughnut-shaped plate divided to plurality out of a blank material by a laser beam processing machine and joining the sectorial pieces to each other to form the doughnut-shaped plate. CONSTITUTION:The sectorial pieces 2 having the shape of the doughnut-shaped plate divided to plurality are cut out of a cold rolled steel sheet 1 by using the laser beam processing machine. Teeth 3 are simultaneously cut out on the outside circumferential surface of the pieces 2. The pieces 2 are laser-welded on a positioning jig to form the doughnut-shaped plate 4. The surface of the plate 4 is thereafter polished.
