BENDING DEVICE AND METHOD FOR DETERMINING AT LEAST ONE MATERIAL PARAMETER AND/OR PROCESSING PARAMETER FOR A WORKPIECE-PROCESSING DEVICE

WIPO Patent Application WO/2020/019011

A3

The invention relates to a method for determining at least one material parameter (19) and/or at least one processing parameter (20) and/or for selecting or creating a processing program for the control system (8) of a workpiece-processing device (10), preferably a bending machine, in particular a press brake or a folding machine, and/or a welding device, in particular a laser welding device, comprising the steps of: (a) removing a workpiece sample (2) of a sheet-like material, in particular sheet metal, preferably from a sheet metal piece (3) or from a charge (4) of sheet metal pieces (3), (b) carrying out at least one measurement on the workpiece sample (2), (c) determining at least one material parameter (19) and/or at least one processing parameter (20) and/or selecting or creating a processing program for the control system (8) of a workpiece-processing device (10) depending on the result of the at least one measurement on the workpiece sample (2), characterized by the step of (d) bending the workpiece sample (2) by means of a bending device (1), the at least one measurement being carried out on the workpiece sample (2) when the workpiece sample (2) is in at least one bent state.
