Evaluation of Nano Fluids with Minimum Quantity Lubrication in Turning of Ni-Base Superalloy UDIMET 720

This article focuses on turning superalloy Udimet 720, which is difficult to work with, using different coolant/lubricant methods. The study includes delivering Graphene and Multi-Walled Carbon Nanotubes nanopowders homogeneously dispersed in vegetable oil the cutting area with minimum quantity lubrication (MQL) method. Experiments at speeds feed rates were repeated four environments. Compared dry turning, zone temperature of fluid delivered by MQL methods decreased. In addition, thanks nanopowders, it formed an film better penetrating tool-chip interface reducing tool’s wear. With reduced tool wear, could maintain its form for a longer period time, so quality surfaces obtained workpiece surface. As result study, was found that improved 30%, wear 51.8% surface roughness 43.9%.
