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

A method for producing a dressing roll and dressing a grinding worm with the dressing roll, comprising the steps of:

• producing the dressing roll by:
• a) producing a disk-shaped base body, wherein the base body is provided with a profiled surface for reception of a layer of abrasive particles, wherein the surface is tooth-shaped in a radial cross section and extends radially from a root region to a tip region,
• b) positioning a layer of abrasive particles on the profiled surface of the base body, and
• c) profiling of the base body which is provided with abrasive particles by removing outer sections of the abrasive particles with a profiling tool so 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 by either increasing or decreasing 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;
• and
• bringing the dressing roll into engagement with the grinding worm to profile a helical grinding profile in the grinding worm.
