Question
An open die forging operation is performed to produce a steel cylinder with a diameter of
9.7mm and a height of 1.7mm. The strength coefficient for this steel is 500MPA, and the
strain hardening exponent is 0.25. Coefficient of friction at the die-work interface is 0.12.
The initial stock of raw material has a diameter of 5mm.
(a) What height/length of stock is needed to provide sufficient volume of material for this
forging operation?
(b) Compute the maximum force that the punch must apply to form the head in this open-
die operation.
