A method for dressing a grinding worm using a dressing roll that engages the grinding worm to profile its helical grinding profile. The dressing roll is produced by: a) producing a disk-shaped base body a profiled surface for receiving a layer of abrasive particles, wherein the surface is at least partially tooth-shaped in a radial cross section, b) positioning the abrasive particles on the profiled surface, c) profiling the base body 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. Production of the profiled surface takes place in step a) so that the distance between the profiled surface and the abrasive profile changes during advancing from the root region to the tip region at a flank of the tooth-shaped surface, measured in the radial cross section perpendicular to the profiled surface.

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.

A method of processing a rotatable assembly is described herein. The method includes mounting a grinding wheel on an arbor to form the rotatable assembly. The grinding wheel has a ring-structure formed from a plurality of grit particles dispersed within a metallic material. The method also includes mounting the rotatable assembly within at least one dressing machine, wherein the rotatable assembly is rotatable relative to a dressing tool within the at least one dressing machine, and shaping the grinding wheel with the dressing tool to define a final outer profile of the grinding wheel configured to machine a workpiece.
