Manufacturing And Production Technology 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 2 mm. The chip thickness obtained is 0.48 mm. If the orthogonal rake angle is zero and the principle cutting edge angle is 90⁰, the shear angle in degree is 36.56 30.56 20.56 26.56 36.56 30.56 20.56 26.56 ANSWER DOWNLOAD EXAMIANS APP
