Abstract
The invention relates to a method for machining a workpiece by means of a laser beam, wherein a laser beam is guided by a beam guiding device over the surface of the workpiece within a working window. The beam guiding device and the workpiece are arranged in such a way that they are movable relative to one another in a direction of displacement along a displacement section and that they can occupy a first and a second relative working position to one another. According to the invention, a point on the workpiece can be machined from the second relative working position, said point being located behind the point which is machined from the first relative working position when viewed in the direction of displacement.
Claims16
A method for machining a workpiece by means of a laser beam, wherein a laser beam is guided by a beam guiding device over the surface of the workpiece within a working window for ablation of material in one or more layers from the instantaneous workpiece surface, the beam guiding device and the workpiece being arranged in such a way that they are movable relative to one another in a direction of displacement for a displacement distance and that they can take in a first and a second relative working position to one another,
- characterized in that
- within one layer, a spot on the workpiece can be machined from the second relative working position, said spot being located behind the spot which is machined from the first relative working position when viewed in the direction of displacement, and characterized in that
- a decision is made for a spot in the overlapping area of the working windows in accordance with a probability function from which relative position the spot will be machined or at which spot the machining from a relative position will stop in order to be continued from another relative position.
