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 20.56 36.56 30.56 26.56 20.56 36.56 30.56 26.56 ANSWER DOWNLOAD EXAMIANS APP
Manufacturing And Production Technology Climb milling is chosen while machining because It enables the cutter to dig in and start the cut The specific power consumption is reduced The chip thickness increase gradually Better surface finish can be obtained It enables the cutter to dig in and start the cut The specific power consumption is reduced The chip thickness increase gradually Better surface finish can be obtained ANSWER DOWNLOAD EXAMIANS APP
