Abstract: A control device controls a table lifting mechanism such that a sheet metal is bent to have a temporary bending angle that is wider than a target bending angle and calculates a first bending angle of the sheet metal bent to have the temporary bending angle. The control device removes a load applied to the sheet metal, calculates a second bending angle of the sheet metal, and calculates a spring back amount. The control device calculates a lowering amount for bending the sheet metal in consideration of the spring back amount and controls the table lifting mechanism to lower an upper table. The control device, after the sheet metal is bent to have the target bending angle, removes the load applied to the sheet metal, and calculates a final bending angle of the sheet metal.
