This paper USES cutting tool with the contact line of conjugatetooth profile based on the principle of the gear engage and generating shape line forming conjugate engage.
The induced normal curvature of two conjugatetooth surfaces along normal direction of contact line is one of the important indexes evaluating mechanical transmission performances.
