As aerospace requirements for low noise and high strength spiral bevel gear transmission continue to increase, tooth surface precise control is becoming increasingly important in design and manufacture. The previous design depended significantly on ease off the tooth surface and using the tooth surface optimization approach. It’s a parameter design technique that goes from the design tooth surface to the target tooth surface without accounting for the reaction of the tooth surface to machine tool machining errors. This study proposes a new algorithm for reverse adjustment of tooth face accuracy control. A mathematical model of the tooth face is initially built using the local synthesis method to replicate the genuine machining process. Second, the machine setup settings are chosen as multi-objective optimization parameters, and the reverse adjustment model is constructed to investigate the machine’s machining error on the tooth surface, as well as the reverse adjustment model’s effects on contact and robustness characteristics. Finally, numerical calculations and comparisons with the findings of existing design approaches are used to verify the validity and effectiveness of the reverse adjustment algorithm in the design of tooth surface accuracy control of curved bevel gears.
