| Abstract: | A new forming technique of sheet metal, laser forming, is introduced, which is a dieless forming technology of sheet by deforming the sheet metal through internal thermal stress induced by partial instantaneous irradiation of a laser beam. Four main forming mechanisms, that is, temperature gradient mechanism, up setting mechanism, bending mechanism and elastic inflating mechanism are explained. The current research at home and abroad and the application of laser forming are discussed. It is held that, with further research, laser forming will be broadly used in auto, aerospace, and national defense industry, etc. |
