A study on CO₂ laser forming of magnesium alloy plate

Abstract

In a laser forming, the plate usually bends to the laser-irradiated side. A method to bend a plate toward the opposite side of laser-irradiated surface is proposed in this report for the purpose of the control of the bending direction. The experiments of CO2 laser forming of Mg alloy plate were carried out under the condition of heating the opposite surface of the laser head. It was confirmed that the plate bended steadily toward the opposite side of laser-irradiated surface by heating, while the bending direction changed at random in the case of non-heating.
