Collaborative machine tool settings compensation considering both tooth flank geometrical and physical performances for spiral bevel and hypoid gears

Abstract

With the increasing demands for low noise and high strength in spiral bevel and hypoid gears transmission, tooth flank optimization considering both geometric and physical performances has been an significant stage in recent design and manufacture. In this paper, a novel collaborative machine tool settings compensation considering both the tooth flank geometric and physical performances is proposed. Firstly, the mathematical tooth flank model is established by simulating the actual generation process. Then, in the tooth flank collaborative optimization design, the geometric constraint on the tooth flank error is developed, as well as the physical constraint on tooth contact performance. Finally, a novel machine settings modification model considering both tooth flank geometric and physical performances is established and solved for the accurate machine settings having the compensation variations. Moreover, the optimal collaborative compensation strategy is provided by using the sensitivity analysis for tooth flank performances. A numerical instance is given to verify the proposed collaborative machine tool settings compensation.
