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 (6) is formed, each groove having two side walls (22,24) substantially perpendicular to a plane tangential to the respective side (4) of the tooth (2), and a second machining step with the removal of shavings, in the course of which the side walls (22,24) of each groove (6) are machined to produce on each side wall (22,24), a cutting edge (26) with an acute cutting angle. The method further teaches that both of the steps for the machining of each groove (6) are achieved by means of a single cutting element (10) which has a trapezoidal profile in a plane perpendicular to the side of the tooth (2), with its larger base facing inwardly of the groove (6) and its smaller base facing outwardly of the groove. The tool for forming grooves with cutting edges in the sides of the teeth of a shaving cutter, comprises a support (12) from which a plurality of parallel cutting elements (10) project, each cutting element having a trapezoidal profile with its smaller base disposed adjacent the support (12). <IMAGE> |
