Non-Traditional Machining Process of Composite Materials using Renewable Lubricants

Abstract

The global increasing alertness of the environmental and health problems linked to the use of mineral based metal cutting fluids in machining is lead industry to develop alternative fluid. The fluid should be environmentally friendly and sustainable like vegetable oil with suspended nanoparticle. The low thermal conductivity of cutting fluids of natural based oil requires the addition of nanoparticles. The most common nanoparticle that suitable to be added to cutting fluid are non-metals, carbide, oxide, Carbon Nano Tubes (CNTs) and metal nitrides. In this paper, a comparison had made of dry machining and machining with cutting coolant oil, sunflower oil+MoS2, Sunflower, oil Graphene. The study concludes that, the addition of such minerals to the cutting fluids increased the thermal conductivity of cutting fluids.
