Efficiency investigations of textured cutting tools in orthogonal cutting of Ti6Al4V alloy: a numerical approach

Abstract

This paper investigates efficiency of micro-textured cutting tools in dry orthogonal turning of Ti6Al4V alloy using 2D numericalanalysis. For this purpose, micro-grooves at different sizes were generated on rake face of cutting tools. Then, orthogonal cuttingsimulations were conducted using different tool rake angle values. Contact length at tool-chip interface, cutting force and force ratioresults were evaluated focusing on performance of micro grooves. The aim was to improve process efficiency and minimize negativeenvironmental impacts by contributing knowledge in development of textured cutting tools. The simulation results revealed thatdecreased forces, force ratio and contact length is possible with use of textured cutting tools. However, improper selection of texture parameters may cause adverse effects such as increased friction. Accordingly, efficiency of micro-grooves relies on both, groove size and rake angle.
