Abstract: A method for controlling a tool, including the steps: providing a reference matrix including reference points and a centering matrix including centering points in a material processing plane; imaging the material processing plane through a camera as a camera image in a size of a camera image field; de-skewing the camera image of the material processing plane by aligning with the reference matrix; scaling a pixel size of the camera image through aligning with the reference matrix; centering the camera image through aligning with the centering points; projecting a processing contour onto the de-skewed and scaled camera image of a workpiece; and aligning the processing contour on the camera image of the work piece and starting the processing, wherein the processing of the work piece is performed though the tool along the processing contour.

Abstract: A method for producing rough surface structures comprising the following step: running a laser beam along filling lines (1) over an area to be processed, wherein the filling line (1) is broken down into particular laser dots (2) with a distance a, and wherein the laser dots (2) are moved in a X direction and in a Y direction in a plane with a random factor b relative to the filling line (1) so that they form a cloud of dots.
