Method for dressing of a grinding worm by means of a dressing roll and dressing roll

A method for dressing of a grinding worm by means of a dressing roll in which the dressing roll, which is provided with an abrasive profile, is brought into engagement with the grinding worm to profile its helical grinding profile,

• wherein the abrasive profile of the dressing roll is at least partially designed tooth-shaped in a radial cross section and extends radially from a root region to a tip region,
• wherein the dressing roll is produced by the steps:
• a) producing of a counterpart which has an inner surface which is at least partially tooth-shaped in the radial cross section;
• b) positioning of a layer of abrasive particles on the tooth-shaped surface and fixing of the abrasive particles by means of a carrier material, wherein the carrier material forms a carrier layer for the abrasive particles;
• c) producing of a disk-shaped base body of the dressing roll and connecting of the base body with the carrier layer including the abrasive particles;
• d) demolding of the base body of the dressing roll including carrier layer and abrasive particles from the counterpart;
• e) profiling of the base body which is provided with abrasive particles by removing outer sections of the abrasive particles with a profiling tool in such a manner that the abrasive profile of the dressing roll is created, wherein
• at the production of the counterpart according to step a) the same is provided with the surface in such a manner that the distance between the profiled surface and the abrasive profile is changing during advancing from the root region to the tip region at least at one flank of the surface, measured in the radial cross section perpendicular to the profiled surface.
