Abstract:
To perform accurate bending processing on a workpiece by matching a ridge line of a punch tip end with a bending line of the workpiece that is generated at first bending processing when the workpiece is subjected to bending processing by double punching.
A press brake 1 performs bending processing on a workpiece W by using a die D installed at a lower table 5 and a punch P installed at an upper table 7 which is movable for positioning relative to the lower table 5.
