Abstract
A method for the dressing of a multi-thread grinding worm by a dressing roll, wherein the grinding worm has at least two screw channels which are arranged parallel to another, which screw channels extend helically around an axis of the grinding worm and wherein the dressing roll has at least two adjacent dressing profiles which are arranged along an axis of the dressing roll, wherein the dressing profiles of the dressing roll are guided simultaneously through adjacent screw channels of the grinding worm during the dressing of the grinding worm. To improve the precision of the dressing the method includes the steps: a) Execution of a first partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through first adjacent screw channels of the grinding worm; b) Execution of at least one second partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through second adjacent screw channels of the grinding worm, wherein the second adjacent screw channels are, compared with step a), offset in the direction of the axis of the grinding worm by at least one screw channel of the grinding worm.
