摘要： A laser beam having a line-shaped beam profile with a following cooling spot in order to increase thermomechanic tension which is moved along a separating line having predefined contours is known in prior art. In order to cut out a given contour using simple mean, (free-shape cut) the method according to the invention relates to a line-shaped burn spot (1) generated on a work piece. Said spot is of significantly increased intensity at both ends (1a, 1b). Said spot is moved along the cut line (2) in such a way that both said ends lie on the cut line (2) and the length (S) thereof depends on the curvature of the contour of the cut line (2).

摘要： In a conventional method, a laser beam, with a linear beam profile and a following cool-spot to increase the thermomechanical stress, is moved along a separating line of predetermined shape. According to the invention, in order to be able to separate any shape (free-form cutting), the method is carried out, whereby a linear focal point is generated, on the workpiece, by means of scanning the laser beam and, during each scanning movement, tracking data for the separation line (2) is generated, such that the linear focal point is given a curvature corresponding to the curvature of the shape of the separation line, by adjusting the scan amplitude.
