Question: bonus problem 9 cemented carbide inserts are used to turn...

Question details

Bonus Problem 9) Cemented carbide inserts are used to turn a part with length 21.0 in and diam Feed = 0.015 in/rev. The parameters in the Taylor equation are n 0.25 and C = 800( operator and machine tool rate $45.00/ eter 4.0 in t/min). The hr, and the tooling cost per cutting edge = $2.00. It takes 5 min to load and unload the work part and 1.50 min to change inserts. Determine the (a) cutting speed for maximum production rate, (b) tol life, and (e) cycle time and cost per unit of product. (10 pt.)
