A 200mm long,75 mm diameter titanium alloy rod is being reduced in diameter to 65mm by turning on a lathe. The spindle rotates at 400rpm, and the tool is travelling at axial velocity of 250mm/min. Calculate the cutting speed, material removel rate, time of cut, power required and cutting force. (hint: the specific energy of titanium ranges from 3.0 to 4.1 W.s/mm^3 , Vc= N*pi*Do, MMR=pi*Davg*d*f*N)
