Abstract

A cutting tool comprising a tool body comprising a shank and a cutter opposite the shank, the body defining a length from a shank end to an end face opposite the shank end, a central axis extends along the length of the body; at least one tooth having a cutting edge, the cutting edge extending along the tooth from the shank to the end face; a flute formed adjacent the at least one tooth; at least one cooling channel formed in the tooth proximate the at least one cutting edge, the at least one cooling channel having an elongated cross sectional shape with an elliptical portion and a circular portion opposite the elliptical portion, wherein the elliptical portion is located proximate the cutting edge.

Method and device for determining the position of a cutting tool relative to the rotational axis of a spindle-mounted workpiece

Patent Williams, Richard R [Oak Ridge, TN]

The present invention is directed to a method and device for determining the location of a cutting tool with respect to the rotational axis of a spindle-mounted workpiece. A vacuum cup supporting a machinable sacrifical pin is secured to the workpiece at a location where the pin will project along and encompass the rotational axis of the workpiece. The pin is then machined into a cylinder. The position of the surface of the cutting tool contacting the machine cylinder is spaced from the rotational aixs of the workpiece a distance equal to the radius of the cylinder.

Tool holder for preparation and inspection of a radiused edge cutting tool

Patent Asmanes, Charles [Oak Ridge, TN]

A tool holding fixture is provided for removably holding a radiused edge cutting tool in a tool edge lapping apparatus. The fixture allows the operator to preset the lapping radius and angle before the tool holder is placed in the fixture and the holder may be removed from the lapping apparatus to inspect the tool and simply replaced in the fixture to continue lapping in accordance with a precise alignment without realignment of the tool relative to the lap. The tool holder includes a pair of self aligning bearings in the form of precision formed steel balls connected together bymore » « less

Internal combuston engine having separated cylinder head oil drains and crankcase ventilation passages

Patent Boggs, David Lee [Bloomfield Hills, MI]; Baraszu, Daniel James [Plymouth, MI]; Foulkes, David Mark [Erfstadt, DE]; ...

An internal combustion engine includes separated oil drain-back and crankcase ventilation passages. The oil drain-back passages extend from the cylinder head to a position below the top level of oil in the engine's crankcase. The crankcase ventilation passages extend from passages formed in the main bearing bulkheads from positions above the oil level in the crankcase and ultimately through the cylinder head. Oil dams surrounding the uppermost portions of the crankcase ventilation passages prevent oil from running downwardly through the crankcase ventilation passages.

Partially turbulated trailing edge cooling passages for gas turbine nozzles

Patent Thatcher, Jonathan Carl [Schenectady, NY]; Burdgick, Steven Sebastian [Schenectady, NY]

A plurality of passages are spaced one from the other along the length of a trailing edge of a nozzle vane in a gas turbine. The passages lie in communication with a cavity in the vane for flowing cooling air from the cavity through the passages through the tip of the trailing edge into the hot gas path. Each passage is partially turbulated and includes ribs in an aft portion thereof to provide enhanced cooling effects adjacent the tip of the trailing edge. The major portions of the passages are smooth bore. By this arrangement, reduced temperature gradients across themore » « less

Turbine engine component with cooling passages

Patent Arrell, Douglas J [Oviedo, FL]; James, Allister W [Orlando, FL]

A component for use in a turbine engine including a first member and a second member associated with the first member. The second member includes a plurality of connecting elements extending therefrom. The connecting elements include securing portions at ends thereof that are received in corresponding cavities formed in the first member to attach the second member to the first member. The connecting elements are constructed to space apart a first surface of the second member from a first surface of the first member such that at least one cooling passage is formed between adjacent connecting elements and the firstmore » « less
