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 disk-shaped base body, wherein the base body is provided with a profiled surface for the reception of a layer of abrasive particles, wherein the surface is at least partially tooth-shaped in a radial cross section,
• b) positioning of a layer of abrasive particles on the profiled surface of the base body,
• c) 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
• the production of the profiled surface takes place according to step a) 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 tooth-shaped surface, measured in the radial cross section perpendicular to the profiled surface.
