Calculate the cost per piece of a milling operation that is used  to machine a pocket of 2”x3”x0.5” (LxWxD).  The material being machined is high silicon aluminium.  The tool material is PCD. 

Assume a labor rate of $50.00/hr and a burden rate of $25/hr.  Assume a surface speed of 2000 ft/min.  The number of teeth on the cutter is 4.  The feed is 0.005 in/tooth.  The depth of cut is 0.020”.  The width of cut is equal to the diameter of the tool (0.5 inches).  Assume a 15% overlap between passes.  The cost per tool is $50.  Use the appropriate Taylor equation/tabulated data in text to determine the approximate tool life.  Assume a tooling cost of $10.  Neglect setup and loading costs.  Assume four parts can be produced per insert.  The time required to index each insert = 0.25 min.  The tool change time is 0.5 min.

After your calculations, explain two practical strategies that you can use to decrease your cost per piece for machining.
