This paper presents an investigation into the Minimum Quantity Lubrication (MQL) and MQL with gamma-Al 2 O3 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-Al 2 O3 nanoparticle dispersed to vegetableoil with volume fraction 1%, the surface roughness decreased about 0.3μm and improved about 15% than pure MQL. Also by dispersing gamma-Al 2 O3 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-Al 2 O3 nanoparticles when it is dispersed in vegetable oil.
