You will soon be meeting with the plant manager and the managers from sales and production scheduling.

They are expecting you to have an answer to the question: Given the need to balance maximizing tool use,

minimizing inventory, minimizing production disruption, and minimizing cost, how many strokes should you

recommend to run this tool before pulling for a regrind?

Create a graph that shows the number of unplanned pulls versus the number of strokes. The graph should

comprise at least six data points. Next, complete the spreadsheet in Figure C$9\mathrm{.}2\mathrm{.}2$ showing the costs of

each individual's plan. Using the graph and the spreadsheet, prepare a response for the question, How

many strokes should the tool be run before pulling it for a regrind? Your analysis should include answers to

the following questions: How will this number balance tool use, cost, inventory, and production disruption?

What are the economics of this situation?
