Minimal quantity lubrication (MQL) machining has been accepted as a successful semi-dryapplication because of its environmentally friendly characteristics and satisfactory performance inpractical machining operations. However, seldom investigation has been done in MQL machining oftitanium alloy at high cutting speeds. In this paper, high speed milling experiments with MQL[removed info]9 ml/hof oil in a flow of compressed air[removed info] have been carried out for a widely used titanium alloy Ti6Al4V.Uncoated cemented carbide inserts have been applied in the experiments. Within the range of cuttingspeeds employed (190 m/min~300 m/min), the cutting performance of MQL has been investigatedwhen peripheral milling the titanium alloy Ti6Al4V in terms of cutting forces, surface roughness, toollife and wear mechanism. The results show that, compared to dry machining, MQL machining bringsabout a significant reduction in cutting forces and surface roughness, and it also gives rise to a notablyprolonged tool life
