Calibration method for a laser machining by forming a reference mark on a workpiece, and a measuring of the offset of these reference mark of a reference point

摘要

Calibration method, including:Determining the position of a focal point (24) of a laser (12) relative to at least one reference element (14) of a working chamber (16), wherein the focal point is the point at which the laser carries out a processing,Form at least one reference mark (36) on a workpiece (20) by means of the laser machining at the focal point, andMeasuring of an offset (40) between a reference point on the workpiece and the at least one reference mark.
