In orthogonal turning of a low carbon steel bar of diameter 150 mm with uncoated
carbide tool, the cutting velocity is 90 m/min. The feed is 0.24 mm/rev and the
depth of cut is 2mm. The chip thickness obtained is 0.48 mm. If the orthogonal
rake angle is zero and the principle cutting edge angle is 90c, the shear angle in
degree is
