摘要:This paper examined the influence of approaching angle on main cutting forces while machining of titanium alloy grade-5 (Ti-6Al-4V) at different cutting speeds and feed rates under dry cutting condition. It has been observed that with increase in cutting speeds, the magnitude of cutting forces and tool tip temperature increase. If both cutting force and temperature level were considered together, the optimum approaching angle works out to be 45o and 90o for 49.5 m/min and 76.7 m/min, respectively. For 116.9 m/min increase of cutting forces at 60o approaching angle can be attributed to low shear angle which is function of the average chip thickness. Positive rake angle produces higher shear angle which leads to the reduction of cutting forces, tool tip temperature.
