Consider the cold drawing of a metal wire that has a final diameter of 0.25 mm. For this metal K = 380 MPa and n= 0.17. The drawing speed is 1600 m/minute. The process has buffers between drawing dies. The friction coefficient is 0.08. The die has an angle (a) of 5 degrees. ● Determine the drawing force (Newtons) for one pass through a die with the maximum reduction in area. (25 points) Determine power required (Watts).
