Abstract
The invention relates to a method for gear shaping a periodic structure, in particular a toothing on a workpiece, in which method the workpiece, continuously rotating about its axis of rotation, is brought into material-removing machining engagement with a toothed shaping tool which rotates about its axis of rotation in rolling contact with the workpiece rotation. After a working stroke, the shaping tool is lifted off from the workpiece in a lifting direction and, after a subsequent return stroke, the shaping tool in the lifted state is returned to the workpiece again for the next working stroke. In the return stroke, a deflection movement of the shaping tool away from the incoming flank of the workpiece and transversely to the lifting direction is superimposed on the rolling contact.
