Based on the space engagement theory, the space position of cutter was analyzed when the tooth profile of a higher-order elliptical bevel gear was generated, a mathematical model of higher-order elliptical bevel gear's tooth profile was established; and then tooth surface equation of higher-order elliptical bevel gear was derived, pseudo-entity and assembly model of higher-order elliptical bevel gear were also acquired. Manufacturing methods by five-axis CNC of higher-order elliptical bevel gear were discussed, by the processing and mesh experimental research of a higher-order elliptical bevel gear pair, comparisons between experimental results and theoretical analysis was made to verify the mathematical model of higher-order elliptical bevel gear's tooth profile, and the feasibility of processing methods shows the processing methods can be used in the actual machining.
