Abstract—Titanium alloy (Ti-6Al-4V) is lightweight, corrosion resistant and high-temperature materials. It has the highest strength to weight ratio of all commonly used metals up to 550 O C. Machining of titanium alloy (Ti-6Al-4V) by milling operation is widely used in the aerospace industry. High-speed machining processes are of growing industry interest, especially due to appealing feature of high cutting speed processes. The cutting speed is considered as one of the most important factors in the success or failure of any cutting processes. The main purpose of machining modeling is to predict reaction forces (RF), stress components at integration points–Mises, and pressure without need to perform many experimental tests. The tests were performed at various cutting speeds while the depth of cut and feed rate remain constant. The prediction by using finite-element modeling method in machining titanium alloy can contribute in reducing the cost of manufacturing in terms of prolongs the cutting tool life and machining time saving.
