The robotic arm receives the commands from the computer, moving and rotating the lens shape against an abrasive wheel, rotating cutter blade or rotating drill thereby duplicating the facet cuts, slots notches or depressions or other designs contained in the computer lens model. Varying pressure is applied by the articulated arm and various degrees of abrasiveness of the abrasive wheel.Type: GrantFiled: January 24, 2005Date of Patent: May 19, 2009Inventor: Virgil T. Yancy

Publication number: 20080183325Abstract: A method of producing holes in a component, in particular of turbomachines, wherein each hole extends from a first, outer surface to a second, inner surface of the component and wherein the method has, for example, the following steps: producing a 3D model of the actual geometry of the component, at least for the region of the holes; adopting each hole on the basis of the actual geometry of the component; generating a production program for each individual hole. In this way, the process quality and with it the quality of the holes increases, because the offset of holes caused by component tolerances is avoided and the drilling funnels are formed according to specification. Furthermore, drilling defects on account of the offset of holes and/or cores can be avoided. Overlapping holes caused by component tolerances are likewise avoided.Type: ApplicationFiled: February 29, 2008Publication date: July 31, 2008Inventor: Josef Kriegmair

Patent number: 7346973Abstract: A processing cell of automatic machining system configured in that it is easy to decide or change the number of steps and to design, and to reduce the installation cost. The control unit of the processing cell comprises an operation data storing means for storing every position necessary data for operation at each position of the processing cell installed in the machining section of the automatic machining system, and a position designating means for designating the after-installation position. The control unit reads necessary data for operation out of the operation data storing means in accordance with the position designated by the position designating means. Thus, the operation of each cell can be switched in accordance with the position, and the processing cells can be easily changed in position and adjusted in quantity.Type: GrantFiled: August 18, 2003Date of Patent: March 25, 2008Assignee: Nissin Manufacturing Co., Ltd.Inventors: Hiroyuki Ooe, Toru Fujimura, Kazuhiko Tsuji, Yasuo Tomita

Patent number: 7252463Abstract: A square channel shaped template of ultra-thin rigid plastic, metal or other material has one or more mating configurations of pencil-point-size marking holes in the two opposing faces of the channel. Each configuration of marking holes matches a configuration of screw holes on a door fixture or door hardware to be mounted on a door. Each configuration of holes may be distinguished by a visible line through the marking holes of each configuration. The template straddles an edge of a door at a measured distance along the edge and fits on the edge with the door closed in a door frame for marking either one or both sides of the door with a mating configuration of marks on the door for drilling.Type: GrantFiled: April 7, 2004Date of Patent: August 7, 2007Inventor: Andrew Valdez

Patent number: 7097394Abstract: In the process of forming a through-hole or blind-hole at desired positions of a the substrate material, the present invention sets a drilling target position for each hole and a plurality of auxiliary drilling positions at a periphery of the drilling target position, and performs a plurality of drillings at the drilling target position and the plurality of auxiliary drilling positions. In another preferred embodiment of the present invention, a plurality of drillings are performed only at the auxiliary drilling positions per one hole at the desired position. According to the present invention, through-holes or blind-holes having several sizes of diameters can be formed by using one drilling jig under a single drilling condition. Accordingly, it is possible to efficiently produce circuit boards at low costs.Type: GrantFiled: October 10, 2001Date of Patent: August 29, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshihiro Nishii, Hiroshi Yamaji, Tadao Kimura

Patent number: 7083368Abstract: A machine having X- and Y-axis linear moving axes and a pivot axis B for rotationally pivoting a pivot member having a tool arranged at a distal end thereof about an axis parallel to a Z axis is controlled. A moving command obtained by a command program commanded by a position expressed by X, Y, and Z in a three-dimensional orthogonal coordinate system is subjected to an interpolation process to calculate amounts of interpolation movement (?X, ?Y, and ?Z) of the respective orthogonal axes. An amount of rotation ?? of the pivot axis required for moving the tool by the amount of movement ?Y in the Y-axis direction is calculated. An amount of correction movement ?x for canceling the movement in the X-axis direction caused by the rotation ?? of the pivot axis B is calculated. Values (?X+?x), ??, and ?Z are outputted to the X axis, the pivot axis B, and the Z axis, respectively.Type: GrantFiled: August 19, 2004Date of Patent: August 1, 2006Assignee: Fanuc LTDInventors: Tomomi Nakazato, Hitoshi Matsuura

Patent number: 7065856Abstract: A machine tool apparatus is provided employing a plurality of tool heads which may be sequentially or simultaneously automatically controlled to perform preprogrammed operations on either the same or different workpieces. In one form, a plurality of tool heads are supported on the same frame, guideway or track and may be separate prepositioned or driven under remote or automatic control to perform preprogrammed operations wither in sequence or simultaneously on the same workpiece or simultaneously on separate workpieces spaced apart on a common conveyor such as a flight conveyor while the conveyor is either in motion or stationary. In another form, the conveyor is automatically stopped with units of work thereon, each disposed so as to be predeterminately located with respect to a respective machine tool which has been prepositioned adjacent the work-holding conveyor.Type: GrantFiled: November 10, 1987Date of Patent: June 27, 2006Inventor: Jerome H.

Patent number: 6971824Abstract: An apparatus for forming features in a workpiece is provided. The apparatus includes a nosepiece that engages a boss of a template and guides a tool member therethrough. The nosepiece includes a housing and an adjustable member positioned at least partially in an interior space of the housing. The adjustable member defines radial apertures that hold locking members such as spherical bearings. The locking members are configured to contact a tapered portion of the inner surface of the housing so that as the adjustable member is adjusted from an unlocked position to a locked position, the locking members contact the tapered portion of the housing and are urged radially inward to retain the boss.Type: GrantFiled: May 6, 2003Date of Patent: December 6, 2005Assignee: The Boeing CompanyInventors: Thomas O.
