Patent number: 8256092Abstract: A tool may be used to form an engine cylinder bore in a compacted graphite iron workpiece using helical interpolation. The tool may be rotated about a first axis while orbiting about a second axis that is parallel to the first axis. While rotating and orbiting, the tool may be advanced into the workpiece. This helical interpolation may be used to successively engage cutting or honing elements of the tool with the workpiece. The elements may thereby be permitted to cool between each successive engagement, which may reduce wear on the tool. Various operating parameters associated with the process may have certain relationships that may be exploited in certain ways to obtain ideal results. For instance, a helical interpolation process may be used to perform an act of rough cutting on the workpiece and finish honing on the workpiece, without having to perform an intermediary step of semi-finish boring.Type: GrantFiled: January 30, 2009Date of Patent: September 4, 2012Assignees: Makino Inc., AB Sandvik CoromantInventors: David C.

The spindle housing includes a rod portion and collar both forged from the rod blank for work-hardened strength of material, and includes attachment holes and the through hole formed by pressing out slugs of material, thus facilitating recycling of scrap.Type: GrantFiled: January 22, 2009Date of Patent: April 10, 2012Assignee: Brunner Manufacturing Co., Inc.Inventor: Ronald E.

Patent number: 8146225Abstract: For forming a clamping ring first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge is formed. The clamping ring is used on a pipe when making a pipe connection.Type: GrantFiled: December 14, 2007Date of Patent: April 3, 2012Assignee: Uponor Innovation ABInventors: Kathryn Marie Olinger, Tim Cota

Patent number: 8141230Abstract: A press-hardened component and a method for producing press-hardened components, in particular a bodywork component, from a semi-finished product made from unhardened, hot-formable steel sheet. Various process steps are carried out in the process. A component blank is formed from the semi-finished product by a cold-forming process, in particular a drawing process. The component blank is trimmed at the margin side to a margin contour which approximately corresponds to the component to be produced. The trimmed component blank is heated and press-hardened in a hot-forming tool, and then the press-hardened component blank is covered with a corrosion-prevention layer in a coating step.Type: GrantFiled: May 29, 2004Date of Patent: March 27, 2012Assignee: Z.A.T. Zinc Anticorosion Technologies SAInventors: Martin Brodt, Roland Wendler, Leonid Levinski, Victor Samoilov

Patent number: 8137062Abstract: A turbomachine includes a housing, and a plurality of turbomachine nozzles. At least one of the plurality of turbomachine nozzles includes a body having a first surface and an opposing second surface that extend between a first end and a second end. At least one of the first and second surfaces includes a profile having an angle of between about 3° and about 8° between a first line passing through the first end and a first position located between about 28% and about 38% from the first end and a second line passing through the first position and a second position located between about 53% and about 63% from the first end, and an angle of between about 10° and about 20° between the second line and a third line passing through the second position and a third position located between about 74% and about 84% from the first end.Type: GrantFiled: May 11, 2010Date of Patent: March 20, 2012Assignee: General Electric CompanyInventors: Xiaoqiang Zeng, Jonathon Edward Slepski, Alexander Stein

Patent number: 8128077Abstract: This invention relates to a tooling system comprising a plurality of elements (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64) having tessellating sides arranged in an array. The elements of the array being movable between a closed position in which the elements contact one another, and an open position in which the elements of the array are spaced apart. In the open position the elements are capable of vertical movement relative to one another. Drive means for opening and closing the array are provided and the elements are mounted on supporting rails (2, 4, 6, 8, 10, 12, 14) and are driven by the drive means between the open position and the closed position along a drive axis which is at angle to the longitudinal axis of the supporting rails.Type: GrantFiled: September 14, 2006Date of Patent: March 6, 2012Inventor: Ben John Halford

Patent number: 8122584Abstract: In a method of producing a honeycomb structure molding die composed of feed holes through which molding material is fed and slit grooves communicated with the feed holes for the use of molding a honeycomb structure body, the slit grooves are formed on one surface of a metal material in a lattice arrangement by repeatedly moving a thin circular grindstone blade which is rotating in a straight-line direction or a line direction approximating a straight line in order to cut the surface of the metal material. In particular, the method removes fine metal powder, generated by cutting the surface of the metal material, using polishing grooves formed in a dressing grindstone disposed in front of the metal material every cutting of the metal material during the slit groove formation.Type: GrantFiled: December 26, 2007Date of Patent: February 28, 2012Assignee: Denso CorporationInventors: Toshiji Kondou, Yuji Yamada, Kunitsugu Mototani
