produce the desired profile by means of generative grinding ideally is the generative grinding u2014 according to fig2 u2014 carried out the polishing grinding follows which is the second and terminal sub step of the hard fine machining for doing so the second machining zone 5 of the hard fine machining tool 3 is used it is essential that also now again a pivoting angle between the axis of rotation a of the gear 2 and the axis of rotation b of the hard fine machining tool 3 is given that however now it is a second pivoting angle u03b2 2 which is different from the first pivoting angle u03b2 1 thus from the ideal pivoting angle which must be given when the ideal geometry of the toothing 1 is ground due to a deviation of the second pivoting angle u03b2 2 from the first pivoting angle u03b2 1 thus at a given difference of angle u03b4 u03b2 it results that an additional amount of removal u03b4s from the tooth flanks of the toothing 1 is removed this situation is shown in fig4 here said amount of removal u03b4s is shown in dependence on the difference of angle u03b4 u03b2 namely for different diameters d of the grinding worm 3 thereby the diameter d 1 is the smallest and the diameter d 4 of the biggest diameter of the grinding worm 3 the characteristic curves which are shown in fig4 can be stored in the machine control or can be calculated and simulated respectively there by means of a stored formula so that it can be accessed to the same when after the generative grinding the polishing grinding has to be carried out at known.
