Experimental analysis and investigations of cooling/lubrication methods for millingof titanium alloys
Titanium alloys have significant applications in aerospace,biomedical and other fields due to their superior properties.However,the cutting conditions are stringentfor milling of such materials.The severe tool wear and low processing efficiency are obstacles.The efficient cooling/lubrication methods canimprove the situation of cutting interface friction.In this study,five kinds of cooling/lubrication methods are taken into account,such as dry cutting,flood cutting,minimum quantity lubrication(MQL),cooling air cutting and minimum quantity lubrication with cooling air(MQL-CA.The experimental machining has carried out on titanium alloy(TC4)with application of these cooling methods.The cutting force,surface roughness and tool wearhavebeen measured to evaluate the machining performance.From the analysis,the insertwasfound with severe worninflood cuttingwhich led to the highest cutting forces.The slight wear wasobserved in cooling air cutting but the highestsurface roughness.MQLsecured the lowest cutting forces and the best surface roughnessbut with thetool wear at certain level.This method showed the cutting forces and surface roughness 20.8%and 55%lower than floodcutting,respectively.This novel research work can be applied for machining of titanium alloys with better quality and efficiency at industry level.
