Determination of Optimal Preform Part for Hot Forging Process of the Manufacture Axle Shaft by Finite Element Method

Abstract

The main objective of this study is to determine an optimal preform part in hot forging process, which can reduce the underfill defect and forging load in hot forging process. The preform design approach was used to design the optimal preform part. The geometrically parametric approach and sensitivity analysis were applied to determine the optimal preform part to form the final part before forging process and the suitable process parameter which have the effect on the material flow by using the non - isothermal condition with finite element modeling (FEM). The fulfilling die cavity was used to be an indicator to determine the optimal preform part. The purpose of this study is to reduce the underfill defect, because the advantage is to improve the productivity rate and production cost at the final forging step. The results of the manufacture axle shaft had been successfully formed by using the optimized preform shape.
