Abstract
Duplex Stainless Steels are one of the newest pioneers in the world of super alloys. They exhibit a unique combination of high strength and corrosion resistance and hence are currently giving a strong competition to other nickel based alloys and titanium alloys. Due to the excessive alloying of DSSs, they have a very poor machinability, as result of which the cutting forces associated with machining is very high. In this work, a 3D Finite Element Modelling of cutting forces in milling of DSS 2205 has been developed using FEM software package ABAQUS Oblique cutting has been used so that inaccuracies due to the assumptions in orthogonal machining are avoided. The developed FEM model has been validated experimentally by conduction a series of milling tests. The model results showed close agreement with the experimental results and the forces values were found to be affected most by feed rate. As feed rate per tooth increases, the forces components were also found to be increasing both for experimental and model values.
