This study is making a product for the development of a process worm wheel of making a shape for gear for worm wheel without hobbing manufacturing process. Because of removing a hobbing process, plastic worm wheel for increased productivity and equivalent quality is produced in this molding, As the result, this important process is to manufacture a EPS worm wheel of small and middle stage cars and hybrid vehicle. Especially, the main goal of this study is as follows. The worm wheel design software of electronic power steeringis developed through this study. CAD file of this software is expressed as design notes and design shape of worm gear for manufacturing of worm wheel.
