Abstract: 

Ultimate surface quality in machining process has a great effect on the workpiece performance and is the most important characteristic of machined surface. Using cutting fluid, as an effective factor on surface integrity improvement, has environmental problems and is harmful for operator’s health. As a result, using minimum quantity lubrication (MQL) is considered as an alternative method. In this study, surface roughness of Ti-6Al-4V alloy workpieces were investigated in high speed milling process and using MQL method. full factorial experiments including 5 levels of cutting speed and 2 levels of feed rate were implemented. Results revealed that a surface roughness of 0.2mm could be achieved in high speed milling of Ti-6Al-4V alloy in proper cutting conditions and in presence of MQL method. furthermore, minimum surface roughness was reported in cutting conditions of Vc=450 m/min and fz=0.08 mm/tooth.
