Problem Statement You are the manager of a workshop. You need to turn 1,500 shafts as an intermediate step in a larger manufacturing process. It takes your workshop technician 20 min to machine a single shaft at a cutting speed of 15 m/min and 10 min to set up the blank in the spindle. Since you are turning 1,500 shafts, the technician will certainly change the cutting tool to maintain quality - a tool change would require five minutes. The...
