Spinning of AISI 304, magnesium alloy and titanium alloy plates is tried with diode laser. The sizes of the plates are 0.3, 0.4 and 0.5 mm in thickness and 70 mm in diameter. The laser beams of maximum power of 140 W are scanned on the lines of 1, 2, 3 mm away from the circumference of the plates. AISI304 plate of 0.3 mm thick can be formed into an end plate of a diameter of 67 mm with a height of 2.0 mm; the bending angle is about 90 degrees. It is difficult to form titanium alloy plates. Magnesium alloy plates are easily formed; however, the surface layer is melted. The spinning characteristics are discussed for AISI304 plates.
