Abstract
The present disclosure relates to a method for dressing a multithread grinding worm, in which a flight of the multithread grinding worm is machined by means of a dressing tool. During machining of the multithread grinding worm, one of several flights of the grinding worm is eliminated, so that the number of flights of the grinding worm is reduced, thereby increasing the service life of the dressing tool and reducing the number of dressing tools to be kept in stock.
Claims17
A method for dressing a multithread grinding worm having a plurality of flights, comprising:
- machining a flight of the grinding worm with a dressing tool, wherein during machining at least one of the plurality of flights of the grinding worm is set back in terms of tooth width and/or tooth height with respect to the original flank, so that the number of flights of the grinding worm is reduced.
A method, comprising:
- with a dressing tool, simultaneously machining a first flank of first flight of a multi-thread grinding worm and reducing the size of a tooth separating the first flight from an adjacent second flight, wherein a second flank of the first flight opposing the first flank is also a first flank of the tooth and wherein a first flank of the second flight is also a second flank of the tooth;
- subsequently, with the dressing tool, simultaneously machining a second flank of the second flight opposing the first flank of the second flight and further reducing the size of the tooth.
A method, comprising:
- with a dressing tool, simultaneously machining a flank of a first flight of a multi-thread grinding worm and reducing the size of a plurality of teeth, each tooth of the plurality of teeth separating two adjacent flights of the grinding worm, and the plurality of teeth separating the first flight from a nth flight of the grinding worm;
- subsequently, with the dressing tool, simultaneously machining a flank of the nth flight which opposes the flank of the first flight and further reducing the size of the plurality of teeth separating the first flight from the nth flight.
