Abstract: A method of sharpening cutting blades of the type made from bar stock type material, the method comprising producing relief surfaces on the cutting profile surface. The method comprises forming first and second relief surfaces (95, 96) on the cutting profile surface. The first relief surface (95) extends from a location inward of the cutting edge (62) to the back face (55) and is oriented at a first relief angle ( beta R) with respect to a side surface (54). The second relief surface (96) extends from the cutting edge (62) to the first relief surface (95) and is oriented at a second relief angle ( beta ) with respect to the side surface (54) with the second relief angle ( beta ) being smaller than the first relief angle ( beta R). The cutting blades may comprise a base portion (51) and a cutting end (52), or, the cutting blades may have a uniform cross section along their length with the front surface of the cutting blade comprising a pair of mounting surfaces (148, 150), rake surface (152) and connecting surface (154). The cutting surface may include a protuberant portion (80) adjacent the top surface (64) of the cutting blades, the protuberant portion (80) also including the first and second relief surfaces (90, 91).

Abstract: Workholding apparatus for mounting a workpiece (6) on a machine tool, the apparatus comprising a diaphragm chuck portion (2) and a tailstock portion (4). The chuck (2) includes a backing ring (70) with face portion (74) attached to the diaphragm (44) with the backing ring (70) having a centering locator guide (76) for centering and stopping the axial advancement of a workpiece in the chuck (2). The chuck (2) also includes a support ring (106) including material (109) located at the periphery thereof for sealing the area between the chuck and the workpiece and dampening vibrations brought about by the machining process. The tailstock portion (4) comprises a rotatable tailstock support (112) having at least one workpiece seating surface (117). The tailstock includes a centering locator guide (114) extending axially from the tailstock support (112) and having a generally curved outer surface (115) for centering the workpiece in the chuck (2). The tailstock portion (112) also comprises an outwardly flaring housing cover (118) including an end flange (124) and sealing means (126) whereby relative axial movement of the tailstock (112) toward the chuck (2) provides for the cover (118) to fit over a workpiece mounted in the chuck with the sealing means (126) contacting a surface of the workpiece radially inward of that portion of the workpiece being machined. The sealing means (126) preventing the introduction of contaminants into the workpiece (6) and chuck (2) and also providing for dampening of vibrations from the machining process.
