A REVIEW ON TURNING OF TI6AL4V ALLOY

Ti6Al4V alloy considered as extremely difficult to machine materials. Titanium and its alloys have several promising inherent properties like low strength-weight ratio, high corrosion resistance etc. but their mach inability is generally considered to be poor. Ti6Al4V is the most widely used titanium alloy. It features good machine-ability and excellent mechanical properties. The Ti6Al4V alloy offers the best all-round performance for a variety of weight reduction applications in aerospace, auto-motive and marine equipment. The main objective of this work is to optimize the surface roughness of Ti6Al4V alloy by precision turning operation. In finishing operation surface roughness is a major concern. This finishing operation will be performed on CNC lathe machineunder lubrication condition. The proposed work is to perform machining under the selected level of cutting parameter to estimate the surface roughness generated as the result. This all result will be analysed in Minitab software
