Abstract

The invention concerns a method for the chip-removing generation or machining of internal gear teeth on a workpiece which is rotatable about its rotary axis and radially delimits a free space that extends axially to one side beyond the internally toothed region and whose radial width narrows in the direction of its axial extension in at least one location. An externally toothed tool which is driven in rotary movement about its axis of rotation is brought from the opposite side into rolling engagement with the internally toothed region with the rotary axes crossed at an angle. Through the application of a mechanical force, the chips which are produced in the process and which are subject to a centrifugal force are caused to change their movement in the zone of narrowing width in a manner directed against the origin of the centrifugal force.
