Abstract
A gear machining method includes: roughing a workpiece while causing a cylindrical hob cutter to rotate in synchronization with a rotation of the workpiece such that a cutting allowance remains; and finishing by cutting off the cutting allowance remaining on the workpiece on which the roughing has been performed during the roughing to form a desired gear shape by feeding a skiving cutter relatively to the workpiece in the rotation axis direction of the workpiece while causing the skiving cutter to rotate in synchronization with the rotation of the workpiece.
Claims6
A gear machining method comprising:
- roughing a workpiece using a cylindrical hob cutter by causing the cylindrical hob cutter to rotate in synchronization with a rotation of the workpiece such that a cutting allowance remains;
- and
- finishing by cutting off the cutting allowance remaining on the workpiece on which the roughing has been performed during the roughing to form a desired gear shape, the finishing comprising feeding a skiving cutter relatively to the workpiece along a rotation axis direction of the workpiece while causing the skiving cutter to rotate in synchronization with the rotation of the workpiece.
A gear machining device comprising:
- a workpiece mounting portion for mounting a workpiece for rotation about a workpiece rotation axis;
- a cylindrical hob cutter mounted to rotate;
- a skiving cutter mounted to rotate and to be fed along a direction parallel to the workpiece rotation axis;
- a roughing controller that causes the cylindrical hob cutter to rotate in synchronization with rotation of the workpiece such that a cutting allowance remains, and
- a finishing controller that feeds the skiving cutter relatively to the workpiece in the workpiece rotation axis direction while causing the skiving cutter to rotate in synchronization with the rotation of the workpiece.
