| Summary: | Application of nanolubricants can improve machining performance since the rolling
action of billions of nanoparticles at the tool-chip interface leads to less friction; which
can produce superior surface quality and longer tool life. The combination of
nanolubricants with minimum quantity lubricant (MQL) systems in machining,
minimize the consumption of lubrication oil; consequently, less pollution will be
caused. Nanolubricants is a lubrication alternative to improve machining output, a cost
saving and less harmful cutting lubricant to human and nature. However, the superiority
of nanolubricants is limited, due to the agglomeration of nanoparticles, which leads to
sedimentation of nanoparticles after a period of time. The addition of a surfactant can
lower the agglomeration of nanoparticles and stabilize the nanolubricants for a longer
period. But, lack of study on the performance of nanolubricants with surfactant
restricted the fundamental understanding on their effect on mechanics of machining
process. Hence, to investigate the effectiveness of aluminum oxide (Al2O3)
nanolubricants with Sodium Dodecylbenzene Sulfonate (SDBS) surfactant,
experimental investigations have been attempted in this study while machining titanium
alloy, Ti-6AL-4V. For a better penetration of nanoparticles into cutting region,
nanolubricants was supplied with MQL system |
