  • Patent number: 10376992
    Abstract: In a method for machining a workpiece by a pulsed laser beam emanating from a tool head, the pulsed laser beam is guided across the workpiece surface in a constant relative position between workpiece and tool head, and the workpiece is machined consecutively in a first and another second relative position. The operating parameters in the second relative position are controlled such that one or more laser pulse hit locations generated in the second relative position have a defined position with reference to one or more laser pulse hit positions generated from the first relative position, particularly lie in a one- or two-dimensional grid defined by plural laser pulse hit positions on the workpiece surface made from the first relative position.

  • Patent number: 10201928
    Abstract: A method for machining a workpiece by means of a laser beam, in which material of the workpiece is removed layer-by-layer according to predetermined definitions to produce a workpiece by traversing the exposed workpiece surface in lengths across the entire surface with a laser beam in order to vaporize and/or combust workpiece material. In a first material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by adjustable mirrors inside the laser tool, more particularly without mechanical control axes being moved to adjust the relative position between the laser tool and the workpiece. In a second material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by means of one or more control axes of the machine, the focal length being variably adjustable by means of a variable optical unit.

  • Patent number: 8240396
    Abstract: The invention relates to a tool that includes a tool holder, which has on its first end a tool holder recess that is adapted to the contours of a rotating spindle driver and a tool recess on a second end that lies opposite the first end. The tool holder also includes a tool head that can be inserted into the tool recess. For the optimal machining of a workpiece, attempts were previously made to provide an oscillating unit in the spindle of the machine, to initiate oscillations in the tool head. The disadvantage of said known constructions is that all available tools have to be synchronized with the oscillation unit. The invention overcomes said disadvantage by equipping the tool holder with an oscillating motor.
