Task 4: The Following are the tasks you are given in the sheet metal forming department: a) A cylindrical part is warm upset forged in an open die. Do = 50 mm and ho = 40 mm. Final height 20 mm. Coefficient of friction at the die -work interface = 0.20. The work material has a flow curve defined by: K = 600 MPa and n= 0.12. Determine the force in the operation (a) just as the yield point is reached (yield at strain = 0.002), (b) at h = 30 mm, and (c) at h = 20 mm. (e) Draw the force as a function of part height and discuss the relationship. v, F II h. he Task 4: The Following are the tasks you are given in the sheet metal forming department: a) A cylindrical part is warm upset forged in an open die.
