ABSTRACT:
It is an object to provide a bending angle detecting system for a press brake which can perform high precision bending process without employing a special die, The bending angle detecting system includes a sensor (20) provided on a back stop (8) for determining a bending position of a workpiece (7) to be subject to the bending process, and means for controlling a lower limit position of a punch (6) based on an angle signal detected by the sensor (20).
