| 20110305918 | Methods for Forming Sheet Metal Components Having Three-Sided Corners and Related Components and Systems - A sheet metal component that is bent from a sheet metal blank includes at least one three-sided corner. Two edges of the three-sided corner are formed by a first bending member of the sheet metal blank bent about a first inner bending radius R | 12-15-2011 |
| 20110220621 | Determining Powder Feed Nozzle Misalignment - This invention relates to a method for determining misalignment of a powder feed nozzle and a laser beam. The method includes forming a test structure on a workpiece in at least two different directions by deposition laser welding with powder at substantially constant deposition parameters without relative rotation between a powder feed nozzle and a laser beam, measuring heights and/or wall thicknesses of the test structure along the test structure, and determining a direction and/or an amount of misalignment of the powder feed nozzle relative to the laser beam based on the measured heights and/or wall thicknesses. | 09-15-2011 |
| 20110116518 | Dynamic Redirection of a Laser Beam - A method for processing workpieces includes performing a laser processing operation in which a laser beam is directed at a first mirror face and at a second mirror face of a redirecting mirror. The second mirror face is at least partially surrounded by the first mirror face. During the laser processing operation, the second mirror face performs a pendulum movement relative to the first mirror face. | 05-19-2011 |
| 20100206857 | Device and Method for Laser Processing - A device for laser processing, in which the device includes: a laser including a resonator, the resonator being configured to generate a laser beam with a predetermined caustic during operation of the device; and an optical element to transform a laser beam generated by the resonator into a transformed laser beam having an annular intensity distribution in a plane perpendicular to a propagation direction of the transformed laser beam during operation of the device, in which the annular intensity distribution extends along the propagation direction of the transformed laser beam, and has, at a minimum diameter of a caustic of the transformed laser beam, a beam radius and a ring width corresponding to 50% of a maximum beam intensity in a radial direction of the transformed laser beam, and a ratio of the ring width to the beam radius is less than 0.6. | 08-19-2010 |
| 20100135356 | Monitoring a temperature and/or temperature related parameters of an optical element - An apparatus for monitoring a temperature and/or a temperature-dependent parameter of an optical element arranged in a path of a laser beam includes a measuring light source to produce measuring radiation and direct the measuring radiation to the optical element, a detector arranged to detect a portion of the measuring radiation that has passed through a passage region of the optical element, an evaluating device connected to the detector to monitor the temperature and/or the temperature-dependent parameter. The evaluating device is configured to determine the temperature and/or the temperature-dependent parameter based on an intensity of the measuring radiation detected by the detector in the passage region. | 06-03-2010 |
| 20100086000 | Laser Discharge Tube Assembly for a Gas Laser and Production Method for the Same - A laser discharge tube assembly for a HF-excited gas laser includes at least two electrodes that are disposed outside of the laser discharge tube, the electrodes are disposed at a separation from the laser discharge tube and are completely embedded in at least one insulating dielectric material. | 04-08-2010 |
| 20100071835 | Fixing Adhered Workpieces - A method for fixing adhesive-bonded includes directing an energy beam upon two or more workpieces and thereby causing localized evaporation of an adhesive disposed therebetween within an effective zone of action of the energy beam; and maintaining a vapor channel in a weld pool within the effective zone of action of the energy beam during the evaporation of the adhesive for releasing gas generated during the evaporation of the adhesive. The adhesive has an evaporation temperature that is less than a melting temperature of a material of the workpieces. The adhesive has a viscosity that substantially inhibits an ingress of the gas generated during the evaporation of the adhesive. | 03-25-2010 |
| 20090271025 | Control of a Machining Tool - The invention relates to a method for distributed control of a machining tool ( | 10-29-2009 |
| 20090120917 | Laser Processing Machines and Methods for Providing a Gas to the Beam Guide of a Laser Processing Machine - ABSTRACT A laser processing machine having a laser processing head that is open to a workpiece has a device for providing gas to the laser beam guide that introduces a first gas through a first gas inlet into the laser beam guide and introduces a second gas through a second gas inlet into the laser beam guide. | 05-14-2009 |
| 20090116939 | Systems for Processing Workpieces and Mechanical Arrangements for Moving Workpieces and/or Workpiece Remnants - A mechanical arrangement for moving workpieces and/or processing remnants from processing of a workpiece comprises a load carrier and a load carrier drive. Part of the load carrier drive is formed by a rigid chain which is acted upon by a chain driving wheel supported on the load carrier. Owing to that action, the chain driving wheel takes the load carrier with it to a target position. In the process, the chain driving wheel moves together with the load carrier relative to a chain abutment against which the rigid chain is braced. Systems for processing workpieces are provided, which make use of a mechanical arrangement of the above-mentioned kind. | 05-07-2009 |
| 20090071946 | Laser processing machines - A laser processing machine is provided which has a machine frame and a laser generator fastened to the machine frame. The laser generator is movable relative to the machine frame. | 03-19-2009 |
