Abstract
In a method of manufacturing gears with rolled or generated tooth flanks by cutting-out tooth slots or spaces with at least one face-mill cutter head performing a rotational movement about a cutter head axis, wherein the production capacity or efficiency is increased in that for rough cutting the tooth slots, during a first working step, the face-mill cutter head and the workpiece perform a plunge-cut movement with respect to one another. Hence, the cutters of the face-mill cutter head initially contact the workpiece at a predeterminable plunge-cut position between end regions of a tooth slot or space which is to be fabricated. For finish cutting the tooth slots, during a further working step, there is performed a generating movement between the face-mill cutter head and the workpiece.
Claims3
A method of fabricating gears having generated tooth flanks by cutting-out tooth slots with at least one face-mill cutter head carrying out a rotational movement about a cutter head axis, comprising the steps of:
- providing a face-mill cutter head and a workpiece at which there are to be cut tooth slots;
- during a first working step for the purpose of rough cutting the tooth slots carrying out a plunge-cut movement between the face-mill cutter head and the workpiece;
- during such plunge-cut movement cutters of the face-mill cutter head initially contacting the workpiece at a predeterminable plunge-cut position between end regions of a tooth slot which is to be fabricated;
- and
- during a further working step for the purpose of finish cutting the tooth slot performing a generating motion between the face-mill cutter head and the workpiece.
