摘要： This invention is a method and apparatus for cutting a workpiece which may have interruptions, with a cutting insert having a cutting edge, where the cutting insert is held in a tool holder and is optionally supported by a shim. Coolant, which may contain liquid nitrogen, is introduced through a passageway to a cooling passage located near the cutting edge. The cooling passage may be located either under, behind, or under and behind the cutting edge. Coolant impacts the wall surfaces of the cooling passage near the cutting edge where it is partly evaporated thereby cooling the cutting insert.

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 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.
