Experimental investigations on tool wear in turning of Ti-6Al-4V alloy under different machining environmental conditions

Experimental investigations on tool wear in turning of Ti-6Al-4V alloy under different machining... This paper deals with the study of tool wear on different cutting tool materials under scanning electron microscope (SEM) and optimisation of process parameters to minimise tool wear in turning of Ti-6Al-4V under different machining environments such as dry, flooded and MQL machining. Optimisation of process parameters is carried out using Taguchi's Robust Design Methodology to minimise tool wear. The results reveal that MQL machining is shown less tool wear as compared to dry and flooded machining. Moderate cutting speed, high feed rate, moderate depth of cut are found to be the optimum conditions and uncoated tool is outperformed as compared to CVD and PVD coated tools. The SEM analysis has been carried out on the worn tools to evaluate the wear mechanisms.

Abstract

This paper deals with the study of tool wear on different cutting tool materials under scanning electron microscope (SEM) and optimisation of process parameters to minimise tool wear in turning of Ti-6Al-4V under different machining environments such as dry, flooded and MQL machining. Optimisation of process parameters is carried out using Taguchi's Robust Design Methodology to minimise tool wear. The results reveal that MQL machining is shown less tool wear as compared to dry and flooded machining. Moderate cutting speed, high feed rate, moderate depth of cut are found to be the optimum conditions and uncoated tool is outperformed as compared to CVD and PVD coated tools. The SEM analysis has been carried out on the worn tools to evaluate the wear mechanisms.
