Manufacturing And Production Technology Which of the following statement is correct regarding grinding of high carbon steel? All of these Aluminium oxide wheels are employed. The grinding wheel has to be of open structure. Grinding at high speed results in the reduction of chip thickness and cutting forces per grit. All of these Aluminium oxide wheels are employed.

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 26.56 20.56 30.56 36.56 26.56 20.56 30.56 36.56 ANSWER DOWNLOAD EXAMIANS APP

Manufacturing And Production Technology Which of the following statement is wrong as regard to down milling? The surface milled appears to be slightly wavy. The coolant can be poured directly at the cutting zone where the cutting force is maximum. The chips are disposed off easily and do not interfere with the cutting. It can not be used on old machines due to backlash between the feed screw of the table and the nut. The surface milled appears to be slightly wavy.
