Laser sheet bending is a new metal forming process realized by thermal stresses resulted from the irradiation of laser beam scanning. Laser forming is a new type of sheet metal forming process. The sheet metal is formed by asymmetrical thermal stresses. The three-dimensional elastoplastic thermomechanical coupled finite element model of laser bending for Ti-6Al-4V plates was established with nonlinear finite element analysis software ANSYS. The bending properties of sheet metal with different processing parameters were simulated. The results show that the twist rotation deformation of sheet metal can be influenced by laser power, spot diameter, scanning velocity, scanning path curvature, and the distance between scanning path and free end.
