A method of dressing a single or multi-start grinding worm, comprising: producing a basic rolling movement between the grinding worm and a gear-like dressing tool (90, 90'); and generating an additional relative movement between the grinding worm and the dressing tool (90, 90'), the additional relative movement being superimposed on the basic rolling movement, wherein generating the basic rolling movement comprises: driving the grinding worm to perform a basic rotary movement around a grinding worm axis; driving the dressing tool (90, 90') to perform a basic rotary movement around a dressing tool axis, which extends crosswise with respect to the grinding worm axis; and producing a shift movement between the dressing tool (90, 90') and grinding worm along the grinding worm axis, wherein the basic rotary movement of the grinding worm, the basic rotary movement of the dressing tool (90, 90') and the shift movement are coupled in such a way that the grinding worm and the dressing tool (90, 90') perform the basic rolling movement during the dressing process, characterized in that the additional relative movement is generated to produce modifications on at least one flank of the grinding worm, and in that an additional rotary movement about the dressing tool axis is superimposed on the basic rotary movement of the dressing tool (90, 90') in order to produce at least part of the additional relative movement, and/or in that an additional rotary movement about the grinding worm axis is superimposed on the basic rotary movement of the grinding worm in order to produce at least part of the additional relative movement, and/or in that an additional axial movement between grinding worm and dressing tool (90, 90') along the grinding worm axis is superimposed on the shift movement in order to produce at least part of the additional relative movement. producing a basic rolling movement between the grinding worm and a gear-like dressing tool (90, 90'); and generating an additional relative movement between the grinding worm and the dressing tool (90, 90'), the additional relative movement being superimposed on the basic rolling movement, wherein generating the basic rolling movement comprises: driving the grinding worm to perform a basic rotary movement around a grinding worm axis; driving the dressing tool (90, 90') to perform a basic rotary movement around a dressing tool axis, which extends crosswise with respect to the grinding worm axis; and producing a shift movement between the dressing tool (90, 90') and grinding worm along the grinding worm axis, wherein the basic rotary movement of the grinding worm, the basic rotary movement of the dressing tool (90, 90') and the shift movement are coupled in such a way that the grinding worm and the dressing tool (90, 90') perform the basic rolling movement during the dressing process, characterized in that the additional relative movement is generated to produce modifications on at least one flank of the grinding worm, and in that an additional rotary movement about the dressing tool axis is superimposed on the basic rotary movement of the dressing tool (90, 90') in order to produce at least part of the additional relative movement, and/or in that an additional rotary movement about the grinding worm axis is superimposed on the basic rotary movement of the grinding worm in order to produce at least part of the additional relative movement, and/or in that an additional axial movement between grinding worm and dressing tool (90, 90') along the grinding worm axis is superimposed on the shift movement in order to produce at least part of the additional relative movement. driving the grinding worm to perform a basic rotary movement around a grinding worm axis; driving the dressing tool (90, 90') to perform a basic rotary movement around a dressing tool axis, which extends crosswise with respect to the grinding worm axis; and producing a shift movement between the dressing tool (90, 90') and grinding worm along the grinding worm axis, wherein the basic rotary movement of the grinding worm, the basic rotary movement of the dressing tool (90, 90') and the shift movement are coupled in such a way that the grinding worm and the dressing tool (90, 90') perform the basic rolling movement during the dressing process, characterized in that the additional relative movement is generated to produce modifications on at least one flank of the grinding worm, and in that an additional rotary movement about the dressing tool axis is superimposed on the basic rotary movement of the dressing tool (90, 90') in order to produce at least part of the additional relative movement, and/or in that an additional rotary movement about the grinding worm axis is superimposed on the basic rotary movement of the grinding worm in order to produce at least part of the additional relative movement, and/or in that an additional axial movement between grinding worm and dressing tool (90, 90') along the grinding worm axis is superimposed on the shift movement in order to produce at least part of the additional relative movement.
