Patent number: 8785811Abstract: Systems and methods are described for efficient laser processing of a moving web-based material. In one embodiment, a moving web is provided at a selected speed. A laser beam is generated having a focal point positioned to provide either a score or cut in the web. The focal point of the laser beam is moved at a speed less than the selected speed for a selected distance thereby producing a discreet score or cut in the web in the machine direction. The focal point is repositioned to form another discreet score or cut once the prior discreet score or cut is formed. The repositioned focal point is moved at a speed less than the selected speed for another selected distance. The step of repositioning is repeated to form a plurality of discreet scores or cuts in the web moving at the selected speed. The laser beam is therefore able to be generated using less power than would be needed to produce the same type of discreet score or cut if the focal point were stationary as the web is moved at the selected speed.Type: GrantFiled: September 28, 2010Date of Patent: July 22, 2014Assignee: Preco, Inc.Inventors: James J.

Publication number: 20140034625Abstract: A system and method is provided to use a laser system to remove excess weld bead build up from a workpiece after a welding operation. After a weld bead is formed a weld bead can have a protrusion which extends above a surface of a workpiece and it is desirable to remove the protrusion. A system and method is provided which uses a laser beam oriented at an angle and delivered with an intensity sufficient eliminate or remove the excess weld bead build up.Type: ApplicationFiled: March 14, 2013Publication date: February 6, 2014Applicant: LINCOLN GLOBAL, INC.Inventor: Joseph A.

Patent number: 8635887Abstract: Methods for separating glass articles from glass substrate sheets are described herein. In one embodiment, a method includes focusing a laser beam on at least one surface of the glass substrate sheet such that the laser beam has an asymmetrical intensity distribution at the at least one surface of the glass substrate sheet. The method further includes translating the laser beam on the at least one surface of the glass substrate sheet along a desired groove line to form at least one groove on the at least one surface of the glass substrate sheet. The at least one groove extends partially through a thickness of the glass substrate sheet along the desired groove line and has bevelled or chamfered walls. The glass article may be separated from the glass substrate sheet along the at least one groove.Type: GrantFiled: August 6, 2012Date of Patent: January 28, 2014Assignee: Corning IncorporatedInventors: Matthew L Black, Ivan A Cornejo, Melinda Ann Drake, Sinue Gomez, Lisa Anne Moore, Sergio Tsuda

Publication number: 20140008339Abstract: A system and method for removing material in a workpiece is provided. The system includes a laser system that melts a portion of the workpiece by heating the workpiece. The system includes a wire feeder system that feeds a wire to the workpiece to remove molten metal from the workpiece by using the wire. The wire is configured such that the molten metal adheres to the wire when the wire makes contact with the molten metal. The melting by the laser system includes a cutting or a gouging of the workpiece. In some embodiments, the system includes a hot wire power supply that supplies heating current through a length of the wire to heat the length of the wire to a desired temperature. The heating of the wire facilitates the adherence of the molten metal to the wire.Type: ApplicationFiled: March 12, 2013Publication date: January 9, 2014Applicant: LINCOLN GLOBAL, INC.Inventors: Jonathan S. Ogborn, Elliott Ash, Edward Enyedy, Michael Barrett

Publication number: 20140007486Abstract: The invention relates to a reticle with a visible pattern in a transparent substrate for a telescope. The pattern of the reticle is made of open grooves which are engraved in a surface of the transparent substrate, wherein the engraved open grooves define groove surfaces at an angle to said substrate surface in which the open grooves are engraved. The groove surfaces have a surface roughness which is large enough to scatter light directed onto the reticle perpendicular to the substrate surface when the reticle is illuminated in transmission mode, such that the pattern becomes visible relative to the remaining substrate surface by said light scattering at the groove surfaces in the transmission mode when viewed from a direction perpendicular to the substrate surface. The reticle is produced with direct laser engraving of the grooves.Type: ApplicationFiled: July 8, 2013Publication date: January 9, 2014Applicant: Carl Zeiss Sports Optics GmbHInventors: Thomas Hornung, Christoph-Hilmar vom Hagen, Juergen Mattern

Patent number: 8624157Abstract: Systems and methods are provided for scribing wafers with short laser pulses so as to reduce the ablation threshold of target material. In a stack of material layers, a minimum laser ablation threshold based on laser pulse width is determined for each of the layers. The highest of the minimum laser ablation thresholds is selected and a beam of one or more laser pulses is generated having a fluence in a range between the selected laser ablation threshold and approximately ten times the selected laser ablation threshold. In one embodiment, a laser pulse width in a range of approximately 0.1 picosecond to approximately 1000 picoseconds is used. In addition, or in other embodiments, a high pulse repetition frequency is selected to increase the scribing speed. In one embodiment, the pulse repetition frequency is in a range between approximately 100 kHz and approximately 100 MHz.Type: GrantFiled: May 25, 2006Date of Patent: January 7, 2014Assignee: Electro Scientific Industries, Inc.Inventors: Jeffrey A.
