Patent
CA 2365490
To improve the speed with which a worksheet is positioned in a press brake, and to further eliminate the need for conventional moving back gauge systems, the present invention replaces the conventional back gauge mechanical system with sensors that non-contactedly determine the positioning of the worksheet, with reference to the bending tools. The thus sensed worksheet position is compared with the desired worksheet location preprogrammed into the CNC controller. Any deviation between the sensed, or the actual worksheet position, with the desired worksheet position for each bend of the worksheet is compensated by further moving the worksheet, until there no longer is any discrepancy between the actual and the preprogrammed desired locations.
