Abstract
In bending a workpiece, a position of the workpiece relatively pressed down by a punch is directly detected by a plurality of position detectors provided in a V-groove of a die, and a bending speed calculation section obtains a bending speed from a change in this position. If bending speeds at position of the respective position detectors differ, a uniform speed arithmetic operation section calculates a bending speed to make the bending speeds at the positions of all of the position detectors, and a driving shaft instruction section controls driving shafts to bend the workpiece at the uniform bending speed.
