Abstract
The invention relates to a method and a laser machining devicefor machining a workpiece. The laser machining devicehas a laserfor generating a laser beam, which is deflected by way of a deflecting devicein accordance with a pattern defined by a control unitand is directed onto a workpiece surfaceof a workpiece, which surface is to be machined. The point of impingementof the deflected laser beamon the workpiece surfaceis guided along at least one spiral path within a circular hatched area. The spiral pathis characterized by spiral path parameters. One spiral path parameter is the line spacing a between neighboring points of intersection P of the spiral pathwith an axis running through the center point M of the spiral path
