Materials Forming: A solid cylinder of uniform circular cross-section is compressed axi-symmetrically to half its initial...
A solid cylinder is compressed axy-symmetrically up to its original height in forging. Calculate the three orthogonal true (log) strains and the von Mises strain. Draw a simple sketch to show the position and the direction of three strains. (10 points) 1.
A 3.00 inch diameter workpiece that is 25 in long is to be turned down to n2.384 inches. Process Specifications: a) Cutting Speed (V) = 300 ft/min, b) Feed (f) = 0.015 in/rev c) Depth of cut (d) = 0.044 in The bar will be held in a chuck and supported on the opposite end in a live center. With this work-holding setup, one end (15 inches) must be turned to diameter; then the bar must be reversed to turn...
