A press brake and a workpiece measuring method in the press brake.

摘要

The present invention is concerned with the folding form of a workpiece (25) between lower and upper dies (6,86) being measured by a workpiece (25) measuring means (6) via a workpiece measuring portion. The depth chasing quantity in a predetermined position of a workpiece (25) is obtained by a folding form operating portion (95) on the basis of the measured folding angle. A crowning quantity is obtained by a crowning correction operating portion (97). Moreover, a depth correction value is obtained by a depth correction operating portion (100) and a left/right balance correction value is obtained by a balance correction operating portion (102). Then, machining is performed on the workpiece (25) on the basis of the obtained correction values.
