Energy Consumption Analysis in Turning Ti-6Al-4V alloy

Abstract

One of the major concerns in manufacturing industries include the amount of energy consumed during machining processes. Therefore, the study of the specific energy during machining must be analyzed in relation to the process parameters (feed rate, speed and depth of cut). This work demonstrates the analysis of specific cutting energy (SCE) and cutting power during titanium alloys machining under dry conditions. Turning experiments with uncoated carbide inserts were performed applying Taguchi Design of Experiments technique and analyzed the effect of speed, feed and depth of cut during turning Ti-6Al-4V titanium alloys. ANOVA was done to find out the influence of the machining parameters on energy consumption. The outcome of this analysis indicates that feed rate is the highly dominant factor responsible for the SCE of a machine tool, whereas, cutting speed was found as the influential factor affecting the power during the machining process. The environmental and economic performance for a machining process may be significantly improved by reducing energy consumption using appropriate machining conditions.
