1. A method for machining a toothing (2) having a right tooth flank and a left tooth flank and an axis of rotation (C), in which a machining tool (4) having an axis of rotation (B) and a tool center (N) is driven in rotation about said axis of rotation (B) to remove material from the toothing, in a machining engagement, while performing relative movement between the machining tool and the toothing in order to produce a flank geometry on the right and left tooth flanks of the toothing that is predefined over a full width of the toothing, said method comprising:
a first machining process, said first machining process comprising carrying out a first relative movement between the machining tool and the toothing in a first machining engagement for producing said predefined flank geometry completely along said full width on one of said right flank and said left flank and along a portion (5) of said full width on the other of said right flank and said left flank of said toothing according to a first controlled movement of the machining tool and the toothing on a machine tool having a controller, said first controlled movement defining a first movement path of the tool center with respect to the axis of rotation of the toothing, said first movement path having a defined axial feeding in the direction of the toothing axis of rotation and a defined axial advancement between the machining tool and the toothing in the direction of the toothing axis of rotation, and
a second machining process wherein said predefined flank geometry is produced along a further portion of said full width on said other of said right flank and said left flank, said second machining process comprising carrying out a second relative movement between the machining tool and the toothing in a second machining engagement according to a second controlled movement of the machining tool and the toothing on said machine tool having said controller, the second controlled movement defining a second movement path of the machining tool with respect to the axis of rotation of the toothing by (1) changing the distance of the tool center from the axis of rotation of the toothing relative to said first movement path so as to move the tool center away from the toothing and (2) carrying out a counteracting compensating correction movement to bring said machining tool into machining engagement with said further portion of said full width on said toothing thereby resulting in changing the first machining engagement to the second machining engagement, to produce said predefined flank geometry along said further portion of said full width,
wherein said first machining process and said second machining process are part of the same machining pass.
