摘要： The present disclosure relates to generating a modified gear flank geometry on an active surface of the workpiece by generation grinding or honing. In at least one example, the modified gear flank geometry of the workpiece may be generated on the active surface of the workpiece by variation of an engagement depth of a tool into the workpiece in dependence on an angle of rotation of the tool. Additionally, the workpiece may comprise a cylindrical spur gear, a helical gear, a spherical gear, or a conical gear. Further, in one or more examples, the modified gear flank geometry of the workpiece includes at least one of a profile waviness or a defined periodic flank waviness.

摘要： 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.

摘要： Provided is an internal gear machining method capable of achieving improvement of machining accuracy and extension of the tool life by increasing a slip velocity. For this purpose, internal gear machining is performed on a workpiece (W) by synchronously rotating the workpiece (W) and a barrel-shaped threaded grinding wheel (11) in mesh with each other. The workpiece (W) is rotatable about a workpiece rotation axis (C1), and the barrel-shaped threaded grinding wheel (11) is rotatable about a grinding wheel rotation axis (B1) having a predetermined shaft angle (Σ) to the workpiece rotation axis (C1). In the internal gear machining method, the shaft angle (Σ) is set large based on the amount of change in a grinding pitch wheel pitch radius of the threaded grinding wheel (11).
