Abstract
A method and an apparatus for skiving a work piece that has a rotationally-symmetric, periodic structure by applying a skiving tool. During skiving, a coupled relative movement of the skiving tool in relation to the work piece is performed. The skiving tool is rotated about a first rotation axis and the work piece is rotated about a second rotation axis. A tilt angle is set during skiving, which has an absolute value that is greater than 15 degrees, and the first rotation axis runs skew with respect to the second rotation axis.
Claims20
A method for skiving a work piece having a rotationally-symmetric, periodic structure comprising applying a skiving tool, the method further comprising:
- coupledly performing a relative movement of the skiving tool in relation to the work piece;
- rotating the skiving tool about a first rotation axis;
- rotating the work piece about a second rotation axis that is skew relative to the first rotational axis;
- and
- setting a positive or a negative tilt angle of the skiving tool during the skiving having an absolute value of greater or equal to 15 degrees.
An apparatus for skiving a work piece having a rotationally-symmetric, periodic structure by applying a skiving tool, the apparatus comprising:
- a skiving tool;
- a tool spindle configured to fix the skiving tool;
- a work piece spindle configured to fix the work piece;
- and,
- numerically controlled drives configured to coupledly perform a relative movement and to coupledly rotate the skiving tool together with the tool spindle about a first rotation axis and the work piece together with the work piece spindle about a second rotation axis,
- wherein the apparatus includes a numerical control or is connectable with a numerical control configured to provide a tilt angle during the skiving having an absolute value of greater or equal to 15 degrees, and the first rotation axis skew with respect to the second rotation axis.
