摘要： A process for preparing the cutting edge of a cutting tool having a rake face and a clearance face. The process comprises the elimination of material from the cutting edge by providing a series of rapidly recurring electrical spark discharges in a gap located between the tool edge and a counterface. The spark discharges vaporize and melt the tool edge to form a desired radius.

摘要： A method of assessing the surface roughness of an object includes directing gas supplied at a constant pressure through a control orifice and subsequently to a measurement nozzle adjacent to and spaced from a surface of the object, with subsequent escape of the gas to the atmosphere. The object is moved past the measurement nozzle and the resultant back pressure of the gas upstream of the measurement nozzle and downstream of the control nozzle is measured to provide a back pressure signal. The frequency content of the back pressure signal is examined to thereby obtain an assessment of the surface roughness of the object.

摘要： Apparatus and method for depositing a corrosion resistant weld clad material upon a cylindrical surface of a workpiece such as the internal cylindrical conduit of a valve body (10). The apparatus includes a turntable (12) having a rotating platform (24) which is adapted for supporting the valve body for rotation about the cylindrical axis of its internal conduit (14). The platform (24) can be tilted from a horizontal position through to a vertical position such that the central axis of the valve body conduit connected thereto can be angled between 30 and 60 degrees. A wire-fed, gas-shielded welding torch (16) is supported adjacent to the cylindrical surface of the conduit (14) to be coated such that as the valve body (10) is rotated by the turntable (12), weld material (82) is deposited circumferentially about the surface of the conduit. The welding torch includes an oscillating mechanism (20) for providing linear horizontal movement of the welding torch head (18) in the generally axial direction of the conduit to provide the desired weld bead configuration and characteristics. Lastly, the welding torch is provided with carriage means (22) for incrementally moving the welding head (18) axially within the conduit in response to each complete rotation of the valve body. In this manner the apparatus and method disclosed herein will cover the entire surface to be welded with a corrosion resistant weld clad material to protect the base material and, therefore, the internal integrity of the valve body.
