Abstract

A process for texturing the surface of a workpiece with a laser beam, the beam being moved by a control unit along a tracking line predetermined by tracking points on the surface of the workpiece to be processed. Desired points that form the midpoints of surface areas are found on the trajectory established on the surface of the workpiece. A tracking point is determined in each of the surface areas. Furthermore, recessed areas and surface areas can be established arbitrarily on the surface of the workpiece, wherein the tracking points fall within the surface areas and not in the recessed areas. Moreover, an imaginary matrix can be formed upon the surface of the workpiece that includes tracking points determined in accordance with a degree of coverage and a random value.
