a. Discuss the bar and wire drawing operation in terms of mechanism, application, and limitation. [3] b. A round rod of aluminum is being drawn from a diameter of 4 mm to 3 mm at a speed of 1 m/s Assume that the frictional and redundant work together constitute 55 % of the ideal work of deformation. Assume K= 205 MPa and n= 0.20 1. Calculate the power required in this operation, and ii. calculate the die pressure at the exit of the die 21230 25-202123n151013) a.

Answer rating: 100% (QA)

SOLUTION a Bar and wire drawing is a metalworking operation used to reduce the diameter of a rod or wire by pulling it through a die The mechanism involves gripping the starting material rod or wire w... View the full answer
