发明名称 METHOD AND DEVICE FOR SEPARATING A FLAT WORKPIECE INTO A PLURALITY OF SECTIONS
摘要 A method of separating a workpiece into a plurality of sections includes generating one or a plurality of lines of modified material along one or a plurality of predefined separating lines in the workpiece in a first step by local material processing using a laser beam through a surface of the workpiece, which results in a reduction of breaking stress of the workpiece along the separating lines, and dividing, in a second step, the workpiece into the sections along the separating lines by thermal laser beam separation, wherein the one or the plurality of lines are generated completely or at least in portions at a distance from the surface in the workpiece.
