A Study on the Forging of Gear-Like Components

This paper describes kinematically admissible velocity fields for forging of gear-like components such as involute spur gear, trapezoidal spline, square spline, serration and trochoidal gear. Half pitch of each gear-like component was divided into several deformation zones with respect to their tooth profile. A neutral surface has been used to represent the inward flow of material during a forging operation by using a hollow billet with a flat punch. By using the suggested kinematically admissible velocity fields, the power requirements were successfully calculated and they were compared with experimental inspections. As a result, the suggested velocity fields are shown to be useful to predict the forging load. The contour of neutral surface varied with the number of teeth.[PUBLICATION ABSTRACT]
