(USCS units) A cylindrical work bar with diameter = 4.5 in and length = 52 in is chucked in an engine lathe and supported at the opposite end using a

live center. A 46.0 in portion of the length is to be turned to a diameter of 4.25 in one pass at a speed of 450 ft/min. The metal removal rate should be 6.75 in/min. Determine (a) the required depth of cut, (b) the required feed, and (c) the cutting time.
