Abstract
A method of forming grooves with cutting edges in the sides of the teeth of a shaving cutter comprises, in order: a first machining step with the removal of shavings, in the course of which a plurality of grooves is formed, each groove having two side walls substantially perpendicular to a plane tangential to the respective side of the tooth, and a second machining step with the removal of shavings, in the course of which the side walls of each groove are machined to produce a cutting edge with an acute cutting angle.

A method of forming grooves with cutting edges in the sides of the teeth of a shaving cutter, comprising, in order:
- a first machining step with the removal of shavings, in the course of which a plurality of grooves is formed, each groove having two side walls substantially perpendicular to a plane tangential to the respective side of the tooth,
- a second machining step with the removal of shavings, in the course of which the side walls of each groove are machined to produce, on each side wall, a cutting edge with an acute cutting angle, and
- wherein both of the steps for the machining of each groove are achieved by means of a single cutting element which has a trapezoidal profile in a plane perpendicular to the side of the tooth, with its larger base facing inwardly of the groove and its smaller base facing outwardly of the groove.
