1. A 150-mm-long, 75-mm-diameter titanium alloy rod is being reduced in diameter to 65 mm by turning on a lathe in one pass. The spindle rotates at 400 rpm and the tool is traveling at an axial velocity of 200 mm/min. The unit power required for cutting titanium alloy is 3.5 W-s/mm³. a) Calculate the cutting speed. (1 points) b) Calculate the material removal rate. (2 points) c) Calculate the time of cut. (1 points) d) Calculate the power required. (2 points) e) Calculate the cutting force. (1 points)
