Abstract
A roughing cutter (14) has a generally cylindrical shank (16) with a plurality of lands (22) and angular flutes (20) with resharpening lips (32) separating the lands. A plurality of straight-crested cutting teeth (24) are formed on the lands with radial relief. Each tooth has a stright cutting edge (28) generally perpendicular to the radial direction. The orientation of the cutting edge permits it to be in parallel relationship to a surface of a workpiece while in cutting engagement. Each tooth has S-shaped side walls (34, 36) with rounded upper portions which are respectively tangential to the crest of the tooth. The rounded upper portions result in reduced power consumption during machining. The teeth of the roughing cutter may be formed by an axially advancing milling cutter with a sloping cutting edge segment (58) and adjoining rounded segments (60, 62).
