In this paper, amanufacturingmethod of the pinionmember of large-sized skew bevel gears using amulti-axis control and multi-tasking machine tool respecting an existing gear member is proposed. First, the tooth surface forms of skew bevel gears are modeled. Next, the real tooth surfaces of the gear member are measured using a coordinate measuring machine and the deviations between the real and theoretical tooth surface forms are formalized using polynomial equations. It is possible to analyze the tooth contact pattern of the skew bevel gears with respect to the deviations of the real and theoretical tooth surface forms by expressing the deviations as polynomial equations. Further, the deviations of the tooth surface form of the gear member are reflected in the analysis of the tooth contact pattern and transmission errors, and the tooth surface form of the pinion member that has good performance mating with the existing gear member is determined. Finally, the pinion member is manufactured by swarf cutting using a multi-axis control and multi-tasking machine tool. Afterward, the real tooth surfaces of the manufactured pinion member are measured using a coordinatemeasuringmachine and the tooth surface form errors are detected. In addition, the tooth contact pattern of the manufactured pinion member and existing gear member is compared with those of tooth contact analysis. The results show that there is good agreement.
