The composite tooth profile which has involute tooth profile at the pitch point and circular tooth profile at the dedendum and addendum is designed to improve the power transfer efficiency and the contact condition than the involute tooth profile with easy machining. The results of this study are as follows.
a. For the same case of whole depth of tooth, the thickness of dedendum of composite tooth profile gear is increased 10.9% than the case of involute gear.
b. The radius of circular arc of composite tooth profile gear is desirable between 1.278 m and 1.478m(m=module).
c. The variation of cutter pressure angle of composite tooth profile gear has no remarkable effect to the thickness of dedendum.
