Abstract:
1. Process for the dressing of a multi-start cylindrical grinding worm ( 4 ) for grinding the tooth flanks of a gear by the continuous generation grinding process, where by the reproduction of a rib profile of a dressing tool ( 2 ) on the grinding worm a grinding worm profile ( 9 ) is produced, wherein the grinding worm profile is produced in that the grinding worm ( 4 ) is pre-profiled by means of a pre-profiling zone ( 7 ) of the dressing tool ( 2 ), said pre-profiling zone ( 7 ) comprising a plurality of first profiling ribs, and in the same set-up of the grinding worm ( 4 ) and the dressing tool ( 2 ) the grinding worm ( 4 ) is finish profiled by means of a, finish profiling zone ( 8 ) of the dressing tool ( 2 ), said finish profiling zone ( 8 ) comprising a plurality of second profiling ribs, pre-profiling being performed in a first machining operation and finish profiling being performed in a second machining operation, and these machining operations being performed separately one after the other.
