Abstract
Aluminium is considered more precious than gold, most commonly used for different aerospace, automotive, and shipping industries. Boring is a critical machining method in assembly operations. This paper investigates the machining performance in machining aluminium 6061 alloy under different cutting conditions through a specially designed mixing nozzle for mist and flood lubrication. Experiments were performed with twenty-seven runs selected from Taguchi robust design and cutting parameters selected from the manufacturer’s recommendation. Results revealed an improved machining characteristic while machining the component with near dry machining compared to dry and flood lubrication. Life cycle assessment of selected functional unit is to investigate the ecological impact using CML baseline method. LCA analysis concluded that dry machining is a more sustainable approach than near dry and flood machining approaches.
