Question
15 A cylindrical workpiece is forged in an open die. The workpiece is 60 mm in diameter and 30 mm
high. The height after forging is 15 mm. The coefficient of friction at the die-work interface is
0.20. The flow curve equation for the workpiece is defined as,
0 = 800 80.2
where o is in MPa. The forging force (in MN) at the end of the stroke is closest to
