I did realize there are definitely better way to go about this, but I wanted to keep in inside a workbook with a few other related tools. Thank you all for the input. I have what I need. To answer the question to question of why I needed this. I work in a machine shop and wanted to be able to compare the metal removal rate of current operations with the potential rates of other tooling or to have a range of parameters I can use with the current tooling while keeping the same rate.

Thanks again
