Abstract: Recently, titanium alloys have received considerable attention due to their excellent corrosion resistance, high strength-to-weight ratio, high strength at elevated temperatures, and biological compatibility. Hence, these alloys are used in a wide range of applications in aerospace, automotive, chemical, and medical industries. The demand of titanium has been steady increasing in aerospace industry because of its excellent strength-to-weight ratio and electrochemically compatibility with the increasingly applied composite materials in aerospace industry. Titanium alloys have outstanding physical-mechanical properties, but they are difficult-to-machine materials because of their high chemical reactivity, poor heat conductivity, low modulus of elasticity, which lead to lower production rates and increased tool wear. newlineTo improve the productivity of titanium alloy components, efforts are made in the diverse areas affecting machinability. Titanium alloys like Ti54M, Ti10.2.3 and Ti5553 are increasingly being used in the aerospace industry. In the near future, Ti54M is likely to replace the Ti6Al4V in the aerospace applications. Among all titanium materials the group of and#946; titanium alloys (Ti10.2.3 and Ti5553) offer the highest strength-to-weight ratio and deeper hardenability. newlineThis study aims at understanding the reasons of good or poor machinability of titanium alloys, through the experimental investigations on Ti54M, Ti10.2.3, Ti5553, and Ti6Al4V alloys. The study also explores the effects of PVD coated tools with varying tool geometries and cutting parameters during interrupted machining of titanium alloys. Experimental studies have been carried out on the selected titanium alloys for understanding the newlinexvi newlinemachinability in terms of cutting and feed forces; cutting tool temperature, and chip morphology. newlineThere are clear indications that the machinability of Ti54M alloy in annealed condition is better than that of and#946; annealed and STA conditions. The experimental studies carried out on Ti10.2.3 alloy in annealed.
