Abstract

1451129 Milling cutters GENERAL MOTORS CORP 6 June 1974 [27 June 1973] 25142/74 Headings B3K and B3B A milling cutter 30<SP>1</SP> for use in milling a curved groove in a workpiece such as a rotor for an I.C. engine, the groove having two parallel sides of different radii of curvature from a common center, the cutter comprising a plurality of circumferentially spaced radially extending teeth 32<SP>1</SP>, having peripheral cutting edges 36<SP>1</SP> lying on a common conical surface of revolution whose vertex 38 is intersected by the cutter axis 31. Each tooth 32<SP>1</SP> has radially extending side cutting edges 42<SP>1</SP>, 44<SP>1</SP> which intersect the peripheral cutting edges and define the width of the groove to be cut, only the side of each cutter tooth closer to the vertex having a relieved cutting edge. Figs. 6 and 7 (not shown) indicate the use of the cutter in a machine tool for milling such grooves in a plurality of rotors for I.C. engines simultaneously as shown in Specification 1,365,439. Reference has been directed by the Comptroller to Specification 1,365,439.
