Method for piercing into metallic workpieces by means of a laser beam and associated laser processing machine and computer program product

摘要

Method for piercing a metallic workpiece (6) at a puncture site (11) by means of a laser beam (5) and a process gas (7), both emerging from a laser processing nozzle (8), during insertion around the puncture site (11) Aufwurf (14) on the workpiece surface (12) is deposited, characterized in that during the insertion of the distance of the laser machining nozzle (8) for Aufwurf (14) is measured continuously and that at least one piercing parameter is changed depending on the measured distance.
