AB  - Machinability of aluminum alloys still represents a challenge due to its tendency to staining andthere is a great need for the development of sustainable solutions for lubrication and cooling. Therefore,researchers are performing intensively to obtain an effective way of machining such alloys. Growth of aerospaceand automotive industries have increased utilization of these alloys day by day. Working for the development ofmore economical and environmentally friendly production technologies has gained increased interest to reducethe environmental and health risks and cost factor caused by the widely used flood lubrication. Vegetable oiland polyol esters are biodegradable synthetic base fluids that can be used as a sustainable alternative topetroleum-derived oils in many lubricant applications. In this study, the effects of castor and canola oils andtrimethylolpropane trioleate (TMPTO) and trimethylolpropane trioleate complex (TMPCX), neopentyl glycol(NPG) and pentaerythritol tetra-oleate (PE-TO) type polyol esters on the machining performance of Al 6061 andAl 7075 alloys were investigated using the Tapping Torque test method. As a result, in the studies performedwith neat fluids, it was determined that PE-TO showed the best performance in Al 6061, while TMP-TOshowed the best performance in Al 7075. In addition, it was found that both vegetable oil types showed lowermetal working performance than polyol esters in both alloys. Since similar results were obtained in themachining of both alloys, 68% emulsions were formulated with these vegetable oils and polyol esters tocompare the machining performance. In contrast to neat machining, On Al 6061, PE-TO showed the mostdramatic performance, while canola oil showed the highest performance. Since Al 7075 has harder machiningconditions than Al 6061, the emulsion machining performance of Al 7075 alloy improved with the coolingeffect of water and gave better results than neat machining.Keywords:
