Finite Element Simulation for Cutting of Ti6AI4V

Lameck Sondo

Abstract: Titanium Ti6AI4V alloy is considered difficult to machine especially at higher cutting speeds, because of inherent properties such as low thermal conductivity, high chemical reactivity with cutting tool materials at elevated temperature, this leads to shorten the tool life and poor quality of the surface finishing of the workpiece being machined. By the use of Finite Element (FE) simulations have reduced the burden of extensive experimental trials in understanding the deformation behavior and optimize the cutting process. In this paper the finite element analysis (FEA) of machining for Ti6AI4V is presented. In this particular case the FEA is applied for both workpiece material and cutting tool material. Then at the end of this paper will be able to model and simulate, thereafter to study the influence of Cutting forces, cutting temperature and tool wear.
