On Numerical Simulations of the Micro-Gears and their Cold Forging Process

In this paper, a parametric cubic spline function for generating gear profile is proposed. The spline function includes new gear design parameters such as pressure angle, number of teeth, module, and tooth tip circle modification. The proposed geometry can improve corner filling condition. Finally, the simulation software DEFORM is used to simulate the cold forging process of the micro-gears with different profiles.
