A hot/cold rolling setup is shown right. The operation first hot rolls a 3/8” thick plate, 12” wide (w), of6061 Aluminum, to an intermediate thickness, then finally through cold rolling, down to 1/4” thick plate.The friction factor μ is assumed to be constant at 0.15 for the hot roll, 0.12 for the cold rolling stage. Thefirst set of rolls operate at 50 RPM. Also ignore any width increase during rolling. CW=13% or .13 What is the plate thickness (mm) prior to the last rolls, t1, if the last set of rollers perform cold work reduction listed below at .13 or 13% Note that 9.52 mm is equal to 3/8 of an inch.
A compound die will be used to blank and punch a large rectangle (90x150mm blank dimensions) out of 6061ST aluminum alloy sheet stock 3.5 mm thick. The diameter of inside hole is 25 mm. The aluminum sheet metal has a tensile strength 310 MPa.

A small connecting rod is forged from AISI 1015 steel at 1200oC. Calculate the forging force in a mechanical press at a speed of 200 mm / s when the die comes into contact with the part. The volume of the connecting rod is estimated to be 28680 mm3, and 20% of the starting material is expected to burn off as flash (flash). In the final form the projected area is 3500 mm2 without flash. The width of the flash is 7.6mm around 300mm in circumference.
