Fluidos de corte a base vegetal para usinagem: tomada de decisão multicritério para ranqueamento com base nas propriedades

Abstract

Nowadays there is a big concern with the environment and with the sustainability of the machining working fluids. The dependence of mineral oil on lubricants industrial activities and its harmful effects on human health increased de discussion about the traditional lubricants, causing a significant increase in research and studies with biolubricant oils. In order to classify and create a ranking of the tested fluids, the present work uses the AHP multicriteria decision analysis method to choose the most appropriate decision method according to the selected criteria. The TOPSIS method was classified as the best option for presenting less computational and simplified way to apply weights, when compared to other methods. Finally, it was verified with TOPSIS method that the U cutting fluid is the most suitable for highspeed machining (HSM) applications because it presents better results and because it is sustainable fluid.
