  • An analytical model to describe the temperature field was established for laser bending of sheet metal.In order to analyze the forming rule of the change to different parameters,a simulation software is programmed on laser scanning sheet metal along the line through the finite element analysis' software-ANSYS.The result shows that the bending angle decreases with the increasing thickness of sheet metal,increases with the increasing width of sheet metal,increases first and decreases afterwards with the increasing laser power,focus diameter or scanning speed if others factors remain unchanged.In addition sheet metal will bend deviating from the laser beam if there is a big thickness or a high scanning speed.Finally,the further academic analysis is carried out on the forming rule of laser bending of sheet metal.

Abstract: An analytical model to describe the temperature field was established for laser bending of sheet metal.In order to analyze the forming rule of the change to different parameters,a simulation software is programmed on laser scanning sheet metal along the line through the finite element analysis' software-ANSYS.The result shows that the bending angle decreases with the increasing thickness of sheet metal,increases with the increasing width of sheet metal,increases first and decreases afterwards with the increasing laser power,focus diameter or scanning speed if others factors remain unchanged.In addition sheet metal will bend deviating from the laser beam if there is a big thickness or a high scanning speed.Finally,the further academic analysis is carried out on the forming rule of laser bending of sheet metal.
