ABSTRACT:
The profiling tool (10) has a segment (12) of a worm thread. Its active zone (13) is coated with grains of hard material (16) and is crowned in cylinder sections coaxial to the tool axis (26). During profiling, the grinding spindle (2) and the tool (10) rotate synchronously. By appropriate correction of the coupling ratio by means of a CNC control when moving the tool (10) in axial direction of the grinding worm (2), the grinding worm flank (1) can be dressed with any desired topology. The method makes it possible to profile topologically modified grinding worms (2) at the grinding worm (2) rotational speed used for grinding, which was previously not possible.
