end shape, and progressively advancing the tool in a radial direction as the wheel continues to rotate, thus machining in the peripheral portion of the annular metal mass a working groove of predetermined transverse cross section. The peripheral portion of the annular metal mass which define the working groove are of a composition which is substantially the same as that of a feedstock metal that is to be extruded in such apparatus when equipped with the wheel member the end shape of the tool is substantially the same as that of an abutment member which is to be used in that apparatus to close the end of an arcuate passageway which is formed in the working groove by a shoe member which cooperates with said cylindrical periphery of the wheel member.

MACHINE
Hein Schmoll, Peter Schubert, Hans Schubert, Klaus Schulze, Heinrich Kutz, Kaarst, Federal Republic Of Germany assigned to SMS Hasenclever Maschinenfabrik GmbH In a forging machine which has four radial rams with respective tools together forming a closed bite, each tool overlaps one adjacent tool and is overlapped by the other adjacent tool, and can be adjusted laterally relative to the radial ram axis, in the operating plane of the rams and tools, for setting the bite size.

PHASE EDGE BONDING OF METAL STRIPS
Paul A Dion, Roderick Dair assigned to Polymetallurgical Corporation A continuous process for solid-phase edge bonding a plurality of dissimilar metal strips to form a composite edge-bonded strip. A plurality of elongated metal strips of equal thickness are heated and aligned in a substantially planar, edge-to-edge relationship and pass through a pair of compression bonding rollers. The bonding roller form a rectangular-shaped cavity having a width slightly greater than the combined width of the plurality of strips and a height less than that of the strips, to reduce in thickness and further elongate the metal strips without substantially changing the combined width of the strips and to form a solid-phase bond between adjacent side edges of the strips. The strength of the solid-phase bond is substantially

equal to that of the parent metal strips such that the composite strip can be cut or stamped to form detail component parts such as electronic lead frames without bond failure.

FOR INDICATING MILL WEAR
END
Jan Jeppsson assigned to The Boeing Company A system is provided for measuring tool wear of a rotating end mill. The system measures wear by monitoring the side-loading forces on the tool during cutting. The resultant side-loading forces FRES have tangential FT and radial FR components. The radial component FR increases correspondingly with tool wear. FRES and FT are measured directly and on the' basis of these measurements FR is determined mathematically to provide an indication of tool wear.
4732551 CONTINUOUS EXTRUSION METALS
OF
John East, Ian Maxwell, Wantage, United Kingdom assigned to Metal Box Public Limited Company A continuous extrusion machine in which feedstock in particulate or comminuted form is admitted to a peripheral groove formed in a rotating wheel member, is enclosed in that groove by a cooperating shoe member, is frictionally dragged along the arcuate passageway formed by said groove and a projecting portion of said shoe member towards an abutment member carried by said shoe member, and is continuously extruded as a metal product through a die orifice disposed at the downstream end of that passageway. A cooling device is provided downstream of the abutment member. The passageway comprises (a) a primary zone extending downstream from the inlet end of the passageway, in which primary zone the particulate or comminuted feedstock is compacted, by rotation of said wheel member, to progressively eliminate voids in the advancing feedstock and so form an agglomerated mass of feedstock metal, and (b) an adjoining, substantially shorter, secondary zone disposed downstream of the primary zone and extending at least to the die orifice, in which secondary zone said mass of metal is progressively compressed, by rotation of
end shape, and progressively advancing the tool in a radial direction as the wheel continues to rotate, thus machining in the peripheral portion of the annular metal mass a working groove of predetermined transverse cross section.
