1. A method for measuring a tool for a generating machining of toothed workpieces, the tool being rotatable about a tool axis and comprising a plurality of cutting teeth, each of the cutting teeth forming a real cutting edge, and the method being carried out using a measuring device, that the method comprising:
(a) calculating a virtual contact point on a virtual cutting edge of a virtual tool, the virtual cutting edge extending along a cutting edge longitudinal direction and having a rounding transversely to the cutting edge longitudinal direction;
(b) calculating a relative orientation between the tool axis and the measuring device as well as a translational relative position between the tool and the measuring device on the basis of the calculated virtual contact point;
(c) setting the calculated relative orientation between the tool axis and the measuring device and the calculated relative position between the tool and the measuring device; and
(d) carrying out a measurement on the real cutting edge in the set relative orientation and relative position.
