Abstract

A method for cutting off an edge portion of a workpiece includes applying a laser to the workpiece to form multiple individual severing cuts in the edge portion such that the edge portion is cut off from the workpiece, the multiple individual severing cuts being arranged together along the edge portion. Applying the laser to the workpiece to form the multiple individual severing cuts includes, for each individual severing cut, translating a laser cutting head and/or the workpiece relative to one another, and detecting, at an end of each severing cut, an edge of the workpiece, in which the translation of the laser cutting head or the workpiece continues at least until the edge is detected.
