3.7 During orthogonal turning of a seamless tube having 32 mm outer
diameter and 28 mm inner diameter, the following data were available:
rake angle −20°, cutting speed 20 m/min, feed rate 0.2 mm/rev, length
of continuous chip from one revolution 50 mm, cutting force 400 N,
and feed force 150 N. Calculate the coefcient of friction, shear angle,
specic cutting energy, and cutting power.
