Abstract
A method of manufacturing a milling cutter having a cutting head and a coaxial integral shank including grinding, in a first grinding operation, a plurality of helical flutes into the outer periphery of a cutter blank from a lead end using a peripheral area of a first grinding wheel generally of frusto-conical profile and rotatable about an axis generally transversely of the milling cutter axis, which peripheral area produces, simultaneously, the following three features: a leading face of a trailing tooth; a rear face on an adjacent preceding tooth; and a swarf removal gullet having divergent sides, grinding, in a second grinding operation, and using a peripheral edge of a second grinding wheel, a relief face, which extends rearwardly from a leading end of a tooth tip, resulting in a minimum tooth wedge angle of approximately 60°, and grinding, in a third grinding operation, a radius on the end of each flute.
