Title:
PRESS BRAKE AND PRESS BRAKE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/085074
Kind Code:
A1
Abstract:
According to the present invention, a control apparatus (NC apparatus (10)) executes control so that bending work is performed on a first sheet metal, which is the first of multiple sheet metals (W), and on a second sheet metal, which is the second or a subsequent one of said multiple sheet metals (W). The control apparatus assesses whether or not the difference between a fourth bending angle formed when temporary bending is performed on the second sheet metal and a first bending angle formed when temporary bending is performed on the first sheet metal is equal to or less than a prescribed angle. If the difference between the fourth bending angle and the first bending angle is equal to or less than the prescribed angle, the control apparatus lowers an upper table (1) by a second depth value used when performing a final adjustment operation on the first sheet metal, or by a corrected depth value obtained by correcting the second depth value according to the difference between the fourth bending angle and the first bending angle, without calculating the amount of springback in the second sheet metal.
