Abstract
A method is for cutting machining of a workpiece using a laser beam. The method includes (a) directing the focused laser beam onto a surface of the workpiece for a formation of a kerf; and (b) removing a material exclusively by ablation. The laser beam has a power density in a focal point of at least 1*107 W/cm. The laser beam has a feed speed taking account of an absorption capability of the material to be removed of at least 150 m/min up to a maximum of 1200 m/min.
