  • Patent number: 8546721
    Abstract: A course of a position of a positioning device is determined as a laser beam welds a workpiece at a focus area of the laser beam. The positioning device is configured to position the focus area of a laser beam on a workpiece such that a joint is formed on the workpiece. A course of the joint on the workpiece from the determined course of the position of the positioning device is estimated, and a deviation between the determined course of the position of the positioning device and the estimated course of the joint on the workpiece is calculated. The deviation represents a parameter related to the precision of the seam position control.

    Abstract: A laser processing machine for processing workpieces, in particular metal sheets, includes a workpiece support and a beam receiver for the laser beam used as a processing tool. The distance between a workpiece lying on the workpiece support and the beam receiver is variable, owing to the fact that the workpiece support and the beam receiver are positionable relative to one another along the beam axis of the laser beam by means of an adjusting drive of an adjusting device with a positioning movement of a variably definable magnitude. A method for processing workpieces, in particular metal sheets, is also provided.

  • Patent number: 8490449
    Abstract: A tool for deburring cut edges on workpieces has a pressure body in the form of a rolling body, by means of which, as relative longitudinal movement of rolling body and workpiece takes place, pressure can be applied to the burr on the relevant cut edge in the direction towards the workpiece while the rolling body rolls along the cut edge. A machine for deburring cut edges on workpieces is provided with a tool of the above-mentioned kind. In the course of a process for deburring cut edges on workpieces, a rolling body is moved along the relevant cut edge with a rolling motion. In that movement, pressure is applied by means of the rolling body to the burr on the cut edge in the direction towards the workpiece.
