Abstract
A method for dressing a grinding worm using a dressing roll that engages the grinding worm to profile its helical grinding profile. The abrasive profile of the dressing roll is at least partially tooth-shaped in a radial cross section and extends radially from a root region to a tip region. The dressing roll is produced by: a) producing a counterpart having an inner surface; b) positioning and fixing a layer of abrasive particles on the tooth-shaped surface; c) producing a disk-shaped base body of the dressing roll and connecting the base body with a carrier layer for the abrasive particles; d) demolding the base body; e) profiling the base body. Step a) includes providing the counterpart with the surface so that the distance between the profiled surface and the abrasive profile changes 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.
