The invention relates to a method for measuring a tool () for roll machining toothed workpieces, wherein a virtual contact points is calculator on a rounded virtual blade of a virtual tool. The relative orientation between the tool axis (B) and the measuring device () as well as a translational relative position between the tool and the measuring device are then calculated and adjusted on the basis of the calculated virtual contact point. The measurement is taken on the real blade in the adjusted relative orientation and relative position, and the measurement can be taken in particular using a cylindrical scanning means in the form of a laser beam, wherein the cylindrical scanning means tangentially contacts the virtual blade in the virtual contact point.

Method and device for measuring a roll machining tool

A tool for hob peeling rotating workpieces having pre-machined teeth comprises a gear-wheel shaped main body and tooth-shaped cutting inserts () which at the end face in the region of the tip circle are disposed on the main body. Each cutting insert comprises at least one cutting tooth. The cutting tooth forms a cutting edge () which runs at least along one of the flanks of the cutting tooth, and a cutting face and a clearance face. The cutting face along the cutting edge is provided with a cutting face chamfer () which in relation to the cutting face () runs so as to be inclined by a chamfer angle. The chamfer angle varies along the cutting edge. Moreover, the cutting edge is rounded by a radius.
