The turning operation was performed using two levels of cutting speed while the feed rate and depth of cut were kept fixed. The SEM images were analyzed for worn tool surfaces and machined surfaces. The microhardness analysis indicated heat-based attention in the turned workpiece; thus, the heat-based effect was lowest in MQL compared to RHVT, compressed air, and dry conditions. Results manifested that MQL can significantly lower tool tip temperature by up to 16 %, tool wear by up to 102%-106%, average cutting forces by 17% -21%, surface roughness reduced by 11% -21%, and energy consumption...

This book has been divided in two stages. In stage I, the aim was to find efficiency of metalworking fluid (MF) strategies for sustainable turning of aerospace aluminum alloy. It was machined employing coated carbide inserts under different environment friendly metalworking fluid (MF) strategies namely dry machining, Ranque-Hilsch vortex tube (RHVT),minimum quantity lubrication (MQL), and compressed air. These technologies were investigated in turning with an attempt to study surface roughness and tool wear. The outcome of research was verified by examining samples of surface roughness and...
