In a gear cutting simulation method and device, a gear-cutting-machine model which specifies relative positions between a blank model and a cutter model is created. A gear model is created as a result of simulation of gear cutting which is performed with the blank model and the cutter model arranged in the gear-cutting-machine model.

A key-engaging part structure which realizes an efficient formation of a key-engaging part in an axial-hole member is provided. A key-engaging through hole is formed in a key-engaging part of an axial-hole member while both and portions of the axial-hole member leave intact such that the key-engaging through hole is bored through the axial-hole member in the radial direction. The key-engaging part is formed using this through hole.
