A method for producing a weakening line in a surface of a component. The method comprises a guiding step and a skipping step. In the guiding step, a removal apparatus for removing a material of the surface is guided over a plurality of segments of a predefined line-shaped contour by means of an activated laser beam in order to produce a desired wall thickness for at least one of the segments so as to produce the weakening line. In the skipping step, the segment is skipped if the segment has the desired wall thickness.
