    摘要： A seal testing apparatus includes a clamp assembly which receives, secures and rotates a piston and seal assembly, a mandrel which extends into the seal assembly and supports a guide which carries a spring biased sensing probe or tooth which is oriented along the axis of the mandrel. In another embodiment, the components are the similar except that the probe or tooth is disposed in the mandrel and extends circumferentially. In both embodiments, data from an optical, laser or acoustic sensor is analyzed to determine the integrity of the piston seal. Yet another embodiment includes an arbor which rotates the seal and an adjacent contra-rotating cylinder having a conical mirror. As the seal, arbor and cylinder rotate, light reflected off the mirror and the seal, and returned to the mirror and a sensor provide data which is again analyzed to determine the integrity of the piston seal.

    摘要： A method and apparatus for improving the surface finish and/or surface integrity of a workpiece formed or shaped with a tool increase the surface hardness of the workpiece during forming or shaping of the workpiece. A method and apparatus for forming or shaping a workpiece also increase the surface hardness of the workpiece during forming or shaping of the workpiece with a tool, as do a method and apparatus for manufacturing a finished part or product from a workpiece. In some embodiments, an expanding jet of cryogen may be jetted to a surface of a workpiece and a tool from a nozzle, wherein the cryogen is at least partially separated into a condensed phase portion and a vapor portion within a downstream portion of the nozzle.

    摘要： A method is provided for assessing chip breaking performance of a selected tool insert used in finish turning for automated machining operations. The method broadly includes the steps for developing a chip groove classification system based upon selected geometric parameters of commercially available tool inserts. Additionally, the method includes creating a fuzzy rule base utilizing the chip groove classification system and actual chip breaking performance data for the commercially available tool inserts. The fuzzy rule base is then used for assessing the chip breaking performance of the selected tool insert. The method takes into account selected geometric parameters, such as, land, primary rake, secondary rake, groove width, groove depth, groove height and slope of backwall.

    摘要： A method of determining the accuracy and repeatability of leak testing instrumentation comprises the following steps: providing a two chamber vessel having an access port and a flow controlling reference orifice associated with each chamber and a third reference orifice communicating between the two chambers, providing a leak testing device and connecting such leak testing device first to one of such ports, pressurizing the associated chamber and, with the associated orifice open, observing and recording the pressure measured by the leak testing device under test as a function of time. The second test repeats this activity with the other chamber and the other orifice. A third test is undertaken with the third orifice open. One of the chambers is smaller and incorporates a smaller orifice and the other chamber is larger and incorporates a larger orifice thus achieving leak testing under different conditions.
