Improved materials for the hob and the advanced coating technique have created a need for testing the dynamic characteristics of dividing error between the worktable and the hob in order to attain both the high-rate and high-accuracy gear cutting. One of the authors has already developed a new apparatus for measuring the dynamic dividing error between the hob and the worktable. Using this apparatus, the dynamic dividing error was measured and recorded not only during the idle running but also during machining. In this report, seven items of testing method for the static and the dynamic torsional rigidity of the rotational transmission mechanism in a hobbing machine, which strongly affects the accuracy of the generated gear, is newly proposed by including the aforementioned method of measuring the dynamic dividing error. The seven items of testing method is carried out on a middle size precision gear hobbing machine which is one of a specific type widely employed in gear production shops. As the result, it was proved that both the high-rate and highaccuracy gear cutting condition applicable on the tested hobbing machine could be identified. The proposed testing method would also be effective for the manufacturers who use many gear hobbing machines, to examine and maintain the generating accuracy of their production equipments. The seven items of testing method proposed would be effectively applied not only to the middle size but also to the small size and the large size gear hobbing machines.
