Abstract
A method for dressing an essentially cylindrical grinding worm on a machine suitable for continuous generation grinding in the diagonal method. The dressing tool is an essentially cylindrical gear wheel, having an abrasive coating on the surface that effects the dressing, which is brought into engagement with the grinding worm to move relative to the grinding worm in axial direction of the same to profile the flanks of the grinding worm. A periodically alternating movement in axial direction of the dressing gear wheel is superimposed on the relative movement of the dressing gear wheel, with the wavelength of the oscillating relative movement being the same or smaller than the usable width of the grinding worm in its axial direction.
Claims5
A method for dressing a grinding worm on a machine suitable for continuous generation grinding of gears in a diagonal method, said method of dressing comprising:
- providing a dressing tool having the form of an essentially cylindrical gear wheel, the dressing tool having an abrasive coating on the surface to effect the dressing;
- bringing the dressing tool and the grinding worm into engagement with one another and moving the dressing tool relative to the grinding worm in the axial direction of the grinding worm to dress the flanks of the grinding worm,
- wherein during the dressing, a periodically alternating movement in the axial direction of the dressing gear wheel is superimposed on the relative movement of the dressing gear wheel, with the wavelength of the resulting oscillating relative movement being the same or smaller than the engagement width Lp of the grinding worm in the axial direction of the grinding worm.
