- Titanium alloys exhibit extraordinary characteristics such as excellent strength-to-weight ratio, superior corrosive and erosive resistance and capability to operate at high operating temperatures. These alloys show poor machinability rating due their low thermal conductivity and high chemical reactivity. This study investigates the machinability of Ti6A14V using TiAIN coated tools by analyzing cutting forces and cutting temperatures. The simulated cutting force data was used to predict the total energy utilized by the process. Cutting tool temperatures during the machining operation were measured by an Infrared (IR) camera with cutting forces experiments. Finite element simulations can offer a cost effective solution when evaluating the machining performance of difficult to cut materials such as Titanium alloys. The study incorporated modified Johnson-Cook constitutive equation and friction model to develop the finite element simulations of the machining process. The finite element simulated results of forces and tool temperature presented good agreement with the experimental results. Copyright
