Influence of Graphene Nanosheets on Thermo-Physical and Tribological Properties of Sustainable Cutting Fluids for MQL Application in Machining Processes

The growing need to increase productivity and pressures for more sustainable manufacturing processes lead a shift less harmful lubrication systems that are nature the people involved. minimal quantity system (MQL) stands out in this respect, especially interrupted cutting such as milling, due interface’s highly dynamic chaotic nature. Using graphene sheets fluids also increases efficiency of machining processes. This work investigates influence on thermophysical tribological properties concentrations 0.05 wt% 0.1 two vegetable-based one mineral-based fluids. first characterized (viscosity, thermal conductivity, diffusivity, wettability) tested reciprocating ramp milling tests; all experiments based norms. results show with (with without graphene) showed better behavior than those dry conditions. alter thermo-physical MQL15 fluid lubricating tests, conditions tribosystem chip–tool–workpiece interfaces, which makes friction coefficient, wear rate stable. Vegetable-based fluids, even minimum quantities nanoparticles, have high potential increasing sustainability process.
