PROBLEM TO BE SOLVED: To eliminate wrong input of die information in a workpiece bending angle measurement apparatus for measuring the bending angle of the workpiece, when applying bending processing to the workpiece using a die.SOLUTION: A workpiece bending angle measurement apparatus 11 is provided for measuring a bending angle of a workpiece, when applying bending processing to the workpiece W by using dies P, D. The apparatus comprises: a camera 19 for photographing die identification information 21 attached to the die and the workpiece that is bent by the die for measuring the bending angle of the workpiece; and a control unit for finding the bending angle of the workpiece by photographing the die identification information with the camera to find the bending angle before correcting the workpiece and associating the found bending angle before correction with the die identification information to correct the angle using pre-stored correction data. |
