A method for cutting workpieces of different thicknesses includes providing at least one unprocessed laser beam, selectively forming a processing laser beam from the at least one unprocessed laser beam in accordance with a thickness of the workpiece, and cutting the workpiece with the processing laser beam. Forming the processing laser beam includes selectively coupling one or more unprocessed laser beams into one or more of a plurality of parallel, non-concentric fibers of a compound fiber, the plurality of fibers of the compound fiber having different cross-sectional shapes. A laser beam characteristic of the processing laser beam exiting the compound fiber differs depending upon which fibers of the compound fiber receive the at least one unprocessed laser beam, the laser beam characteristic of the processing laser beam differing depending on the thickness.

A method is provided for manufacturing a mold for injection molding, especially for injection molding of optical components of automotive lighting devices. The method includes at least the following steps: providing a mold body, laser milling a pattern into a surface of the mold body, and coating the surface of the mold body by electroless nickel plating.

A supporting device for supporting a workpiece for processing in a laser processing machine includes a base carrier having a guide body for fastening the supporting device in the laser processing machine, and a guide device provided on the base carrier for guiding the workpiece. The guiding device includes at least two guide elements, which are adjustable in distance to one another and on which the workpiece rests. The guide device has two slides, which are movable relative to the base carrier. At least one of the at least two guide elements is provided on each slide. The two slides are movable in coupled fashion, along two guides that are arranged at an angle to each other and are provided on the base carrier.

Methods of separating a glass web include exposing a separation path on the glass web to a laser beam that produces thermal stress along the separation path without damaging the glass web. The methods further include redirecting a portion of the laser beam to create a defect on the separation path while the separation path is under thermal stress produced during the exposing the separation path on the glass web to the laser beam, whereupon the glass web separates along the separation path in response to creating the defect. Apparatus are further provided for separating a glass web with at least one laser beam generator that produces a laser beam to heat a separation path and a mirror configured to reflect an end portion of the laser beam to create a defect at a location of the separation path on the glass web.

The invention relates to a system and to a method for coating workpieces using a coating device, which is designed to apply a metal coating to a surface of the workpiece.

A three-dimensional laser machine includes a machine head, a controller for positioning the machine head and controlling an orientation of a nozzle, and a sensor for detecting a distance between a workpiece and the nozzle. The controller is capable of performing a profile control of correcting the position of the machine head based on the detected distance. When the machine head has reached a predetermined position part way through an approach process of moving the machine head from an approach start position to a machining start position while controlling the pose of the nozzle, the controller performs the profile control to move the machine head to the machining start position.
