There are a lot of factors influencing hobbing accuracy because hobbing is intermittent cutting and its generating motion is complex. These factors are geometrical, kinematical, dynamic or cutting mechanismic, and the errors of a hobbed gear are usually dependent on the combined effect of the factors. On the other hand, it is not easy to exactly measure the errors of the generating motion between the hob and gear biank. For these reasons, it is difficult in general to determine the valid influencing factors and to decide on a method of improvement when an engineer is facing a problem with hobbing accuracy. In this paper, a developed analysis method, which can conveniently calculate the errors of a hobbed gear in three dimensions by the action of an individual or a combination of various influencing factors, is proposed. Some useful information for improving hobbing accuracy may be obtained by applying the method to comparing and analyzing the measured data with calculated ones. It is also confirmed that this method is valid because the calculated error curves are in good agreement with measured results.
