This paper presents an investigation into the Minimum Quantity Lubrication (MQL) and MQL with gamma-Al2O3 nanoparticles in end milling processes of AISI D3 steel work material to analyze the effects of cutting parameters on surface roughness with taguchi method. The experimental results show when gamma-Al2O3 nanoparticle dispersed to vegetable-oil with volume fraction 1%, the surface roughness decreased about 0.3μm and improved about 15% than pure MQL. Also by dispersing gamma-Al2O3 nanoparticle to vegetable oil with volume fraction 2%, surface roughness decreased about 0.5μm and improved about 25% than pure MQL. This results indicate better performance application of gamma-Al2O3 nanoparticles when it is dispersed in vegetable oil.
