    • The invention relates to a method for determining distance correction values (∆A) for the desired distance between a laser machining nozzle (8) arranged on a laser machining head (3) and a workpiece (6) during the laser machining of said workpiece (6), in which method, during the laser machining process the distance (A) of the laser machining nozzle (8), which is moved along a desired movement path, from the workpiece (6) is measured capacitively and controlled to the corrected desired distance. In said method, according to the invention the workpiece (6) is scanned both by means of the laser machining nozzle (8) and by means of a measuring head (11) arranged on the laser machining head (3) in place of the laser machining nozzle (8), said measuring head having a lower lateral sensitivity of capacitance measurement than the laser machining nozzle (8), each scan being carried out with a pre-set desired distance and the scanning movement path of the laser machining nozzle (8) is thus determined. The distance correction values (∆A) for the desired distance of the laser machine tool (8) along the desired movement path during the laser machining of the workpiece (6) are then calculated from the movement paths that have been determined by means of the laser machining nozzle (8) and the measuring head (11).
    • 提供了方法,机器,和工件的激光处理期间,用于在激光加工头的激光加工喷嘴与工件之间的期望距离的确定性采矿距离的修正值的计算机可读介质。 在一些实施方式中,工件被沿单独工件的激光加工喷嘴和测量头就位在激光加工头的激光加工喷嘴的排列,电容测量的距离相同于表面的所希望的路径扫描 所需的距离。 测量头具有电容测量比激光加工喷嘴的下侧的灵敏度。 激光加工喷嘴和测量头的相应扫描运动路径是确定性的开采。 用于激光加工喷嘴的所需距离的距离校正值然后确定性从与激光加工喷嘴与测量头开采的扫描运动路径确定性开采。
