Question details

A rectangular metal piece measuring 1000 mm x 5000 mm x 2000 mm (width x height x length) is designed to be forged in a 40 MW press. The height will be reduced by 30% and the piston speed will be u = 1.5 m / min The mechanical properties of the material are described by parameters K = 315 MPa, n = 0, 54, C = 450 MPa and m = 0.1. The coefficient of friction is estimated at μ = 0,5. Will you choose cold or hot forging? Document your answer with calculations.
