Abstract

Numerical simulation is becoming an important tool for forming process development. In the field of metal forming, bulk forming has been widely analysed. In this paper, numerical simulations are conducted to analyse the process of Incoloy 901 forward extrusion. The FEA simulation was carried out using Forge3, a FEA software, specifically produced for metal forming simulation. An axisymmetrical 3D geometric model of tools and billet was constructed for the analysis. The extrusion speed was varied and also the extrusion die angles. The influence of die angle, reduction ratio, ram speed, die temperature on the extrusion force during the extrusion process were investigated. Results show that die angle, ram speed, die land diameter has a significant influence on the extrusion force evolution. The simulation results confirm the suitability of the current finite element software for modeling the three-dimensional extrusion of aluminum billets..
