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.
Method for gear shaping a periodic structure comprising a toothing (2) on a workpiece, in which method the workpiece, continuously rotating about its axis of rotation (C2), is brought into material-removing machining engagement with a toothed shaping tool (8) which rotates about its axis of rotation (C8) in rolling contact with the workpiece rotation, and, after a working stroke (A-B), the shaping tool is lifted off (B-C) from the workpiece in a lifting direction (A2) and, after a subsequent return stroke (C-D), the shaping tool in the lifted state is returned (D-A) to the workpiece again for the next working stroke,
Control program which, when implemented on a controller (99) of a gear shaping machine (100), controls said gear shaping machine so as to carry out a method comprising gear shaping a periodic structure having a toothing (2) on a workpiece, in which method the workpiece, continuously rotating about its axis of rotation (C2), is brought into material-removing machining engagement with a toothed shaping tool (8) which rotates about its axis of rotation (C8) in rolling contact with the workpiece rotation, and, after a working stroke (A-B), the shaping tool is lifted off (B-C) from the workpiece in a lifting direction (A2) and, after a subsequent return stroke (C-D), the shaping tool in the lifted state is returned (D-A) to the workpiece again for the next working stroke,
Gear shaping machine (100), in particular with lifting cams (24) in a shaping head with crank drive, with a controller (99) which controls the gear shaping machine in at least one operating mode for carrying out a method comprising gear shaping a periodic structure having a toothing (2) on a workpiece, in which method the workpiece, continuously rotating about its axis of rotation (C2), is brought into material-removing machining engagement with a toothed shaping tool (8) which rotates about its axis of rotation (C8) in rolling contact with the workpiece rotation, and, after a working stroke (A-B), the shaping tool is lifted off (B-C) from the workpiece in a lifting direction (A2) and, after a subsequent return stroke (C-D), the shaping tool in the lifted state is returned (D-A) to the workpiece again for the next working stroke,
