Abstract
A tool includes a first tool member having first machining blades which are formed on an outer circumferential surface of a first tool body and which perform first machining on a workpiece gear and a second tool member having second machining blades which are formed on an outer circumferential surface of a second tool body and which perform second machining on the workpiece gear. The tool is formed such that, in a state in which the first tool member and the second tool member are combined, the first machining blades of the first tool member protrude toward the second tool member and the second machining blades of the second tool member are positioned at predetermined intervals in a circumferential direction relative to protruding portions of the first machining blades.

1-19. (canceled)
A tool having a plurality of machining blades, comprising:
- a first tool member including first machining blades formed on an outer circumferential surface of a disk-shaped first tool body so as to be parallel to a rotation axis of the first tool body, the first machining blades performing first machining on a workpiece;
- and
- a second tool member including second machining blades which are formed on an outer circumferential surface of a disk-shaped second tool body so as to be twisted with respect to a rotation axis of the second tool body and which have a blade length along a direction of the rotation axis longer than that of the first machining blades such that a machining point with respect to the workpiece is movable, the second machining blades performing second machining on the workpiece,
- wherein, in a state in which the first tool member and the second tool member are combined such that the respective rotation axes of the first tool body and the second tool body are coaxial with each other, the machining blades of one of the first tool member and the second tool member are formed so as to protrude toward the other of the first tool member and the second tool member and the machining blades of the other of the first tool member and the second tool member are positioned at predetermined intervals in a circumferential direction relative to protruding portions of the machining blades of the one of the first tool member and the second tool member.
