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.

Abstract: The invention concerns a method for the machining of the tooth edges between an axially facing surface and the tooth flanks of a gear with a machining tool that has a toothed contour. For the material-removing cutting operation, the machining tool, rotating about the axis of its toothed contour, is brought into rolling engagement with the toothed workpiece under a crossing angle different from zero between the rotary axes of the machining tool and the toothed workpiece.

Abstract: The invention relates to a method for gear shaping a toothing (55) with a specified normal pitch (mn), angle of action (α), and optionally a helix angle (β) on a workpiece (50), wherein a shaper cutter (40) moving in stroke cycles with a specified stroke length (h) removes material from the workpiece in multiple working strokes in a rolling machining engagement, thereby forming contact tracks, wherein the contact track on the partial circle in the stroke center runs at an angle (γ) to the flank line (57) at least for a first plurality of strokes, the cotangent of said angle being smaller than or equal to the product of a constant of 40, preferably 33, in particular 25, and a geometry/process factor.

Abstract: The invention relates to a method for shaping a periodic structure, in particular a toothing on a workpiece, wherein a lifting mechanism lifts the shaping tool, within the working stroke, off of the workpiece for the return stroke after a machining operation, characterized by a rotational angular region of the lifting cam functionally assigned to a circumferential cam profile region of a lifting cam, the same driven to rotate by a motor, of the lifting mechanism, which circumferential cam profile region determines the engagement distance between the shaping tool and the workpiece in a working stroke portion of a stroke cycle, wherein the rotational angular region of the lifting cam is passed through a further time—albeit in the opposite direction of rotation—during the same stroke cycle.

Abstract: The invention relates to a machine for the gear cutting machining of workpieces, in particular a gear shaping machine, comprising a spindle for holding a machining tool, and a drive by means of which the spindle can be rotationally driven about its spindle axis, and further comprising an arrangement. When said arrangement is actuated, a spindle rotation caused by the drive changes the axial relative position with respect to the spindle axis.
