Sustainable machining: environmental performance analysis of turning

The manufacturing sector accounts for 40% and 25% of global energy resources consumption respectively. Machining is one the most power-intense operations in making a significant contribution to environmental footprint. purpose this study identify key parameters that contribute towards impacts conventional turning. A set experiments was designed using Taguchi L9 method. Experiments were performed analyse electrical consumption, metalworking fluid (MWF) surface roughness, material removal rate during turning AISI P20 with both wet dry machining. life cycle assessment (LCA) conducted assess performance multi-response optimisation optimum operating conditions. results show machining yields better compared LCA reveal highest contributor under impact categories, while effect MWF negligible. use workpiece cutting insert significantly aquatic ecosystem resource depletion damage categories. Further, proposed considering impact.
