Abstract: A bending machine includes hydraulic cylinders capable of adjusting an inclination state, eccentric shaft units, and a control device. The control device sets an inclination state of the upper table and also sets a curved state of the lower table to conform to the inclination state of the upper table in order to carry out partial bending to pressurize a limited pressurized range compared to a pressurized range in which a workpiece is pressurized by using entire areas of an upper tool and a lower tool in a lateral direction. The control device changes a combination of the inclination state of the upper table and the curved state of the lower table and repeats the partial bending while causing a transition of the limited pressurized range in order to carry out entire area bending to pressurize the workpiece over an entire area in the lateral direction.
