Sustainability is a growing interest in basic industry. The ultimate goal for manufacturing industry is environmental releases, and sustainable development. By reducing energy consumption, economic and environmental performance can be significantly improved for the manufacturing systems. In this paper, the cutting force and specific cutting energy (SCE) consumption are evaluated based on the calculated material removal volume. Three different cutting tool geometries, including the C-, D-, and T-shaped turning indexable tools, are examined to investigate how cutting tool geometry affects the cutting force and SCE. Experimental research and theoretical modeling analysis have been conducted. Statistical analysis for theoretical and experimental SCE has been conducted to extract the effect of each factor on variation. Results of this research show that the more volume of cutting tool involved into the workpiece, the smaller the SCE produced. Optimal setting for sustainability target in terms of minimum cutting energy being consumed could be obtained through the established model.
