METHOD FOR CUTTING OR MACHINING INTERNAL GEAR TEETH, MOTION CHANGING DEVICE AND MACHINE TOOL

摘要

The invention relates to a method for cutting or machining internal gear teeth of a workpiece that can be rotated about its rotational axis and radially delimits a free space which extends axially on one side beyond the internally toothed section and the radial extension of which tapers in at least one portion in the direction of extension. An externally toothed tool which is driven to rotate about its rotational axis is brought into rolling engagement with the internally toothed section from the other side and at a crossed-axes angle, the motion of chips that are produced and that are subject to a centrifugal force being changed by mechanical force in the region of the tapered portion contrary to the origin of the centrifugal force.
