Definition of the face gearing with a conical involute pinion starts with the basic rack. The pinion and the face gear are obtained as the result of true conjugate generation, with generating action described by the equation of meshing. The limiting conditions of undercutting, interference and pointing on the face gear tooth are determined. A new method is proposed for continuous generation of the face gear with an intermediate member, which, together with state of the art CNC technologies, allows practical grinding, hobbing or shaving of the face gear. A mathematical model is established which relates the basic plane, the pinion, the intermediate member and the face gear with true conjugate action, thereby determining the relative position and motion between any two of the four members. Design considerations are discussed. A numerical example is given.
