Drilling, Machinability, Titanium Alloy, Ti6Al4V, Chip Morphology
Titanium is light in weight, strong, highly corrosion resistant, bio compatible, and non magnetic. As titanium processes low specific gravity and high specific strength, titanium and its alloys are used mainly in aerospace, automotive, marine and petrochemical industries. Among all the alloys of titanium, Ti6Al4V is the most widely used alloy. Between the chip of titanium and tool face, high coefficient of friction exists which makes machining of titanium and its alloys difficult. After reviewing many research papers it was noticed that to improve drilling performance of titanium alloy high pressure supply of coolant is desirable. TiAlN coating for carbide tools is considered the most appropriate for drilling. Lower cutting speeds and peck drilling to be employed to achieve better tool life. Other important conclusions drawn from intense literature review have been summarized below. Several researchers have established co-relation among cutting parameters and chip morphology.
