Orthogonal Cutting of Ti6Al4V Alloy Using Experimental and Theoretical Analysis

Abstract:

The current paper deals with the orthogonal cutting of Ti6Al4V alloy. Initially, the cutting process is simulated using the Finite Element Method (FEM). Various cutting conditions including cutting speed and feed rate are considered. Based on this computational analysis the chip creation mechanism is studied. The simulation results describe adequately the chip generation and flow, delivering quantitative data concerning temperature and stress distribution, as well as chip geometry. In addition, orthogonal cutting experiments are conducted on a CNC lathe machine with the same cutting conditions. The experimental results are compared with the analytical ones and useful conclusions regarding the chip formation can be drawn.
