Dhabl Polytechnie Assignment-4 Manufacturing process (EMEM 303) OLYTECHNIC Q.2 A 300-mm-wide strip 25-mm thick is fed through a rolling mill with two powered rolls each of radius 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min. The work material has a flow curve defined by K 275 MPa and n -0.15, and the coefficient of friction between the rolls and the work is assumed to be 0.12. Determine if the friction is sufficient to permit the rolling operation to be accomplished. If so, calculate the roll force, torque, and horsepower
