The invention makes a tool available, which allows highly precise, simultaneous production of two back-tapers on the tooth flanks of the teeth of a workpiece in the form of a gearwheel, independent of their width. For this purpose, the invention provides that the tool includes a tool carrier configured in elongated manner, in the manner of a journal, and oriented coaxial to its central longitudinal axis of the tool, and includes at least two blades, which come into engagement with the tooth to be machined, in each instance, removing chips during use, wherein the blades are held on the tool carrier at a distance from one another in the longitudinal direction of the tool carrier and extend over a partial length of the tool carrier, in each instance, in terms of their width. According to the invention, in this regard the position of at least one of the blades is adjustable in relation to the other blade, so as to balance out deformations of the tool carrier that occur during use. The invention also states a method for simultaneous production of at least two back-tapers on the teeth of a workpiece in the form of a gearwheel, by means of a tool according to the invention.

A method for producing a bevel on the edge defined by an end face of a gearwheel and the flanks of the teeth of the gearwheel adjacent thereto, with a cutting tool which at least includes a cutting edge. The invention further relates to a cutting tool for performing the method and a cutting insert, a device for performing the method and a control program. It is essential that the cutting edge processes only one processing section of the edge during each revolution of the cutting tool.

A method for simultaneous production of at least two back-tapers on the teeth of a workpiece in the form of a gearwheel using a tool that includes a tool carrier configured in elongated manner, in the manner of a journal, and oriented coaxial to a central longitudinal axis of the tool, and at least two blades, which come into engagement with the tooth to be machined, removing chips during use, wherein the blades are held on the tool carrier at a distance from one another in the longitudinal direction of the tool carrier and a width of the blades extend over a partial length of the tool carrier. The position of at least one of the blades is adjustable in relation to the other blade, so as to balance out deformations of the tool carrier that occur during use.

A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the cutter head includes positive blade seating surfaces (16, 18) and the capability to clamp the blades (8) tight to the positive seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

A bevel gear manufacturing face cutter head (2) for face hobbing and face milling. The cutter head has blade positioning slots (20) having a four-sided shaped cross-section and positive blade seating surfaces (22, 24). The cutter head also has the capability to clamp cutting blades (8) tight to the positive blade seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.
