用于在激光加工工件时求取间距修正值的方法和相应的激光加工机
摘要：
在一种用于求取在激光加工工件(6)时布置在激光加工头(3)上的激光加工喷嘴(8)和工件(6)之间的额定间距的间距修正值(ΔA)的方法，其中，在激光加工时电容式地测量沿着额定运动轨迹运动的激光加工喷嘴(8)与工件(6)的间距(A)并且将该间距调节到修正后的额定间距，根据本发明，以激光加工喷嘴(8)以及以取代所述激光加工喷嘴(8)地布置在所述激光加工头(3)上的测量头(11)分别在预给定一个额定间距的情况下走过所述工件(6)并且在此确定所述激光加工喷嘴(8)走过的运动轨迹，该测量头具有比激光加工喷嘴(8)小的电容测量横向灵敏性。由以激光加工喷嘴(8)和以测量头(11)确定的运动轨迹求取在激光加工工件(6)时激光加工喷嘴(8)的额定间距的沿着额定运动轨迹的间距修正值(ΔA)。
摘要（英）：

Methods, machines, and computer-readable mediums for determining distance correction values of a desired distance between a laser processing nozzle on a laser processing head and a workpiece during laser processing of the workpiece are provided. In some implementations, the workpiece is scanned along a desired path of a surface of the workpiece separately by the laser processing nozzle and a measurement head arranged in place of the laser processing nozzle on the laser processing head, with a capacitively measured distance identical to the desired distance. The measurement head has a lower lateral sensitivity of a capacitance measurement than the laser processing nozzle. Respective scanned movement paths of the laser processing nozzle and the measurement head are determined. The distance correction values for the desired distance of the laser processing nozzle are then determined from the scanned movement paths determined with the laser processing nozzle and the measurement head.
