In this study star-shaped wheel means the wheel with triangular teeth. The object of this study is to decide the positions of the pitch circle to generate the hob profiles for cutting starshaped wheels. By calculation the envelope of the teeth of wheel on rack which makes rolling contact with the pitch circle of the wheel was obtained, and under the condition in which the envelope can exist the allowable range of the position of the pitch circle was decided.<BR>The graph showing the relation among tooth angle, number of teeth, root circle radius and pitch circle radius of the wheel was drawn to faciliate to decide the position of the pitch circle.
