The gear is a major mechanical element for the power transmission between two adjacent axes. Even though tooth profile of the gear is made of involute and cycloid curve, involute curved gear is generally used by the easiness of the fabrication and assembly. There are lots of studies for the gear design but mostly weighted toward to the drawing production and two dimensional modeling. And because the exclusive three dimensional gear design program is costly high, it is only used at the very confined fields. In this study, we developed automatic gear design program to create three dimensional model and gear profile of the spur and helical gear with involute tooth profile by using user development program named Visual LISP on the AutoCAD and compared each gear tooth profile which is created by automatic design program and commercial program named KissSoft, Inventor utilizing exclusive reverse engineering program named RapidForm XOV and performed gear fabrication through wire cutting electric discharge machining and after that, we compared gear measured data which was made by three dimensional scanner and made by the fabricated gear to check accuracy of the gear profiles. And also checked interference and undercut of the gear tooth by using gear driving motor.
