With Means To Precisely Reposition Work Patents (Class 409/174)
  • Patent number: 8784021
    Abstract: A jig device holding a work piece is used with a milling machine that cuts from the work piece a prosthesis having a surface essentially free of defects. The jig device is inserted repeatedly into the machine in the same predetermined location, even upon inverting the jig device. This maintains the spatial relationship between the jig device and milling so, at start up, they are always in the same exact spatial relationship. The milling machine partially cuts through a first side of the work piece to form in the work piece a cavity having a surface part corresponding to at least a portion of the prosthesis being made. The jig device is then removed from the machine, inverted and reinserted into the machine at the same predetermined location. A support material is placed in the cavity prior to reinserting the jig device. Upon reinserting the jig device, the machine precisely cuts through an opposed side of the work piece to form within the work piece a prosthesis having a surface essentially free of defects.

  • Publication number: 20110236146
    Abstract: Assembly and method for machining an object with a milling machine. The object needing machining on various sides so as to require clamping. It is proposed to mechanize this time-consuming operation. To this end a further clamp is attached to a conversion or turning station which may clamp the already partially machined object with an already partially machined side thereof. The mutual positioning of the clamp in which the object is located and the clamp wherein the object is transferred, is precisely defined and by the linear movement of the clamps in relation to each other, the object may be transferred. The additional clamp is configured to receive the object to be machined in precisely the desired position, without damage. Subsequently, a further clamp is again put into the milling machine with the aid of a robot so that other sides of the object can be further subjected to a milling operation.

  • Patent number: 7707705
    Abstract: Metallic guide elements having a functional area are made from profiled blanks by hot forming the profiled blanks and subsequently milling in a high speed milling cutter system the profiled blanks by a position-controlled milling cutter head with milling disks of a great diameter, wherein in the step of hot forming the profiled blanks are matched with regard to a cross-sectional mass distribution of the profiled blanks, respectively, to the subsequent step of milling such that by a partial cutting removal in the areas of the profiled blanks that become the functional area of the guide element narrow dimensional tolerances are produced. The material flow of the profiled blanks within the high-speed milling cutter system is controlled autonomously by an integrated stacking device that has manipulators and turning stations.

  • Publication number: 20090238654
    Abstract: The invention relates to a method for tooth-machining of workpieces (3), especially gear wheels, comprising milling, deburring by hobbing and integrated secondary deburring. The method proceeds on a machine tool (1) having two workpiece spindles (11, 12) which may exchange places. A workpiece (3) is mounted on a first workpiece spindle (11), followed by the workpiece spindles (11, 12) exchanging places, followed by pre-milling and, where applicable, cutting (=deburring by shaving) of the workpiece (3), followed by a further exchange of places, followed by chamfering and cutting of the workpiece (3), followed by a further exchange of places, followed by a finish-milling of the workpiece (3), followed by a further exchange of places, followed by a workpiece change. At the same time, the same procedure takes place on the second workpiece spindle (12), staggered in time by an exchange of places of the workpiece spindles (11, 12).

  • Patent number: 6612789
    Abstract: The system constructed according to the present invention operates by properly positioning a base compact disc (CD) onto a cutting table and then cutting the CD to a preprogrammed shape. Base CDs are stacked on an elevator system. The CDs include one side on which data is recorded, and another side on which the CD label is printed. A robotic arm with a vacuum gripper then picks-up a CD from the stack and moves the CD to a cutting table. While the arm moves the CD, a machine vision system takes a picture of the CD label and compares the picture to an image of the label stored in data. An image mapping program then determines the rotational orientation of the CD by comparing the picture and data image. Once the orientation of the disc is known, the robot arm rotates the disc a calculated amount so that it can then be placed on the cutting table in a proper normalized orientation. The CD is held in place on the cutting table by a vacuum chucking system.

    Abstract: In an actuator, a carriage coupled to an item to be displaced with a translatory movement comprises a follower element which defines contact surfaces engaged against the flanks of the thread of a micrometric screw. The contact surfaces co-operate with the thread of the screw only over a small angular portion thereof. The follower element of the carriage is held on the thread of the screw by resilient thrust means acting on the carriage so as to urge it pivotally about an axis (X--X) which is parallel to its direction of translatory movement, being prevented from moving in all the other degrees of freedom. The actuator is especially adapted for use in translator devices in which the level of precision is of the order of a micrometer.
