Experimental and statistical investigation of the effect of cutting parameters on surface roughness, vibration and energy consumption in machining of titanium 6Al-4V ELI (grade 5) alloy

Abstract

This study aims to increase energy efficiency in turning operation. For this purpose, titanium 6Al-4V ELI (grade 5) alloy is turned to obtain optimum surface quality with minimum energy. For this reason, in order to determine the appropriate cutting conditions, cutting speed, feed rate and depth of cut have been chosen according to the cutting tool suitable for titanium material. In the turning process, surface roughness, vibration and energy consumption were measured. In Taguchi analysis, S/N ratios, S/N graphics, S/N response table, ANOVA results, pareto analysis results, it is determined that the effective parameter in surface roughness, vibration and energy consumption is feed rate. It has been observed that the surface roughness and energy consumption increase as the vibration value increases. The created Taguchi models have made estimations with a high percentage of accuracy (Surface roughness is about 82%; vibration is about 89%; energy consumption is about 98%).
