  • Patent number: 8770567
    Abstract: A work piece supporting device is disclosed for limiting vibrations caused by work piece processing. The device comprises a base portion having a plurality of openings therein. Each opening forms a well with an inner boundary and a peripheral surface extends therefrom. A plurality of elongate supports are each arranged to be located in a corresponding well for supporting the work piece when positioned above the base portion. A resilient support is positioned in the well between the inner boundary and the elongate support. The elongate support is movable between a first position in which the resilient support is in a relatively less compressed configuration to a second position in which the resilient support is in a relatively more compressed configuration.

  • Patent number: 7860601
    Abstract: A system and method are disclosed for quickly characterizing the profile of a surface of a processed workpiece using a non-contact scanner, such as a laser scanner, in preparation for subsequent machining. The method determines the location of a plurality of features of a processed workpiece on a machine tool, and includes steps of reading a first list of approximate feature locations, defining a scan path based on the first list, scanning a profile of the workpiece along the scan path and calculating an actual location of each feature of the plurality of features based on the profile. The system and method are well suited to determine the location of features such as holes in welder header boxes.

  • Patent number: 6099215
    Abstract: A device for establishing a seal between a pair of articles, has a first resilient member arranged to be positioned between the articles, so that the first resilient member and the articles collectively form a first chamber. A vacuum supply is provided for supplying a vacuum to the first chamber. A pressure supply is also provided for applying a pressure to the first resilient member to force the first resilient member against both of the articles.
