A steel billet with a rectangular cross section is being forged using a die with a width of 84.5 mm. The billet has an original thickness of 46.0 mm and a width of 273 mm. The billet is upset to a thickness of 28.0 mm and the coefficient of friction for the workpiece-die interface is 0.234. Take the strength coefficient (K) as 526 MPa and the strain-hardening exponent (n) as 0.225. a) Determine the maximum die pressure (do not use average pressure formula). Expected answer: 1050 MPa b) Determine the required forging force (use average pressure). Expected answer: 16200000 N
