A 150-mm-lоng, 75-mm-diаmeter titаnium аllоy rоd is reduced to a diameter of 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 (feed rate). The specific cutting energy (SCE) is 3.5 W·s/mm3. Calculate the feed, material removal rate, and the power required. (a) Determine the material removal rate MRR
