A high-speed steel tool is used to turn a steel workpart that is 500 mm long and 70 mm in diameter. The parameters in the Taylor equation are: n = 0.2 and C=75 (m/min) for a feed of 0.4 mm/rev. The operator and machine tool rate = $40.0/hr, and the tool cost with 4 cutting-edges is $20.0. It takes 5.0 min to load and unload the workpart and 3.0 min to change tools. Find (a) cutting speed for maximizing the production rate, and (b) tool life for minimizing the cost. с - 16-17 Tmin= -64-1)(C+“) n C.
