2. How long would it take to turn 6 in of 1-in bar stock on a No. 3 Warner & Swasey turret lathe running at 300 ft/min and feeding at the rate of 0.005 in/r? 3. A plain milling cutter with 3-in diameter and a face width of 2 in is being used to mill a piece of cold-rolled steel 1.5 in wide and 4 in long. The depth of cut is 3/16 in. How long will it take to make the cut if the feed per tooth is 0.010 in and a 16-tooth cutter running at a surface speed of 120 ft/min is used? 4. Compute the times for elements a, b, c, d, and e when a + b + c is timed at 0.057 min; b + c + d is timed at 0.078 min; c + d + e equals 0.097 min; d + e + a is 0.095 min; and e + a + b is 0.069 min
