Abstract

Cutting fluids are widely used in machining process, to remove heat from the cutting zone. Minimization on usage of cutting fluid is more focused by present day industrialists and researchers for the economical and ecological reasons also. To address the above concern, Minimum Quantity Lubrication (MQL) is one of the techniques, which uses less cutting fluid to maximize the product quality and tool life. The present work reports the experimentations carried out under Minimum Quantity Lubrication and dry conditions in turning of AL 6351-T6 alloy. The samples were turned out at five different spindle speeds (77, 184, 252, 673 and 922 rpm), and the effect of spindle speed on tool temperature and surface roughness are investigated here. It was found that increase in spindle speed in turning of AL6351-T6 alloy by using MQL reduced the surface roughness compared to dry condition.
