Unformatted text preview: m; rolling temperature = 210 C. 3. - Estimate the force required for deep drawing an aluminum sheet (Y = 150 MPa and 1 mm thickness) with a blank of diameter 25 mm and a punch of diameter 20 mm. What is the final height of the cup? Is it possible to perform this process? Please explain. (Note: please use the equations shown in class which are different from the book). 4.- Plot the force vs. reduction in height curve in open-die forging of a solid cylindrical, annealed copper specimen 2 in. high and 1 in. in diameter, up to a reduction of 70%, for the cases of (a) no friction between the flat dies and the specimen, (b) = 0.25, and (c) = 0.5. Ignore barreling and use average-pressure formulas....
