Sustainability Issues in Turning Process: A Study in Indian Machining Industry

Abstract

Manufacturing industries are crucial in a country's economy. However, they accounts for huge resource consumption of and waste excretion. The objective of this study was to investigate sustainability issues pertinent to turning process in a Indian machining industry. Parameters such as surface roughness, material removal rate and energy consumption were considered as sustainability factors. The effect of process parameters (speed/feed/depth of cut), the machining environment (dry/MQL/wet) and the type of cutting tool on the response was observed. Analysis of Variance (ANOVA) was applied to test the data. The process was analysed using response surface methodology (RSM). The results of the study helped to understand the effect of the cutting parameters on surface finish, energy consumption, and material removal rate. The process was optimized from power consumption point of view. Extended form of the model could be useful to predict the environmental impact of machining process which will bring environmental concern into conventional machining.
