Hey Mortek,
I second Xeno's suggestion, but add that if you can't find an Iscar sliderule, Kennametal has one as well. The Kennametal version also calculates horsepower, force etc.
I created a spreadsheet in Excel using the basics from the sliderule, and inputting variables that are dictated by the job or machine, ie; material, tool, rpm's etc. I have been thinking of refining it to include force and horsepower to maximize the metal removal rate of my programs instead of just "that looks right".
