Modelling and simulation of three-roll bending process of bimetal Circular Billet

Abstract

Bending process is an important metal forming technique which is used on industrial scale. An asymmetric three-roll bending is sub-type bending process and has a simple configuration. The present study has focused on the investigation of the bonded bimetal billet. The two material consist of copper alloy rod inside an aluminium alloy (AA 6061-T6) tube with one common dimension between the rod and the tube which is the radius of rod and the inner radius of tube. The effect of varying the radius has considered on this study. The results shown that the increasing of copper alloy radius increased the reaction load and the mass of the bimetal billet with exponential increment.
