PROBLEM TO BE SOLVED: To provide a cutting method for a spiral bevel gear which sets a tooth space into an arbitrary shape and obtains a smooth tooth flank with no step without causing of the problem of under cutting. SOLUTION: The shapes of tooth space sections S1-S5 are set at a plurality of positions between one end of the tooth space 33 to be cut and the other end, and the movement of an arm shaft and the rotation of a chuck are controlled so that a tool 16 moves from the one end to the other end passing through each tooth space section S1-S5. Such movement of the tool is repeated to form the spiral tooth space 33. COPYRIGHT: (C)2004,JPO
