Question 91. In orthogonal turning of a bar of 100 mm diameter with a feed of 0.25 mm/rev, depth of cut of 4 mm and
cutting velocity of 90 m/min, it is observed that the main (tangential) cutting force is perpendicular to the
friction force acting at the chip-tool interface. The main (tangential) cutting force is 1500 N. The orthogonal rake angle of the cutting tool in degree is

Question 100. During the electrochemical machining (ECM) of iron (atomic weight = 56, valency = 2) at current
of 1000 A with 90% current efficiency, the material removal rate was observed to be 0.26 gm/s. If
Titanium (atomic weight = 48, valency = 3) is machined by the ECM process at the current of
2000 A with 90% current efficiency, the expected material removal rate in gm/s will be
