Abstract:
1. A method for skiving a work piece having a rotational-symmetric, periodic structure utilizing a skiving tool, the method comprising the following steps performed before skiving: rotating the skiving tool about a first rotation axis, coupledly rotating the work piece about a second rotation axis with said rotation of the skiving tool, radially feeding the skiving tool in a direction toward the work piece to bring the skiving tool in contact with the work piece for a first time, infeeding the skiving tool in a radial plunging motion in the direction toward the work piece from the moment of the first contact down to a predetermined depth, wherein at least during the infeeding step the first and second rotation axes are skewed relative to each other, and upon reaching the predetermined depth, advancing the skiving tool by axially advancing the skiving tool in the direction of the second rotation axis and differentially advancing the skiving tool relative to the rotating work piece at least during the infeeding of the skiving tool, wherein the first and second rotation axes are also skewed relative to each other during the advancing step.
