1. A cylindrical work bar with 15 mm in diameter and 150 mm length is chucked in an engine lathe and supported at the opposite end using a live center. A 125 mm portion of the length is to be turned to a diameter of 14 mm one pass at a speed of 150 m/min. The metal removal rate should be 125 cm3/min. Determine (a) the required depth of cut, (b) the required feed, and (c) the cutting time.
