I took the recommended chip thickness right out of the Taig manual. If I
remember correctly, it listed a range of 0.005 - 0.010" so I picked on the
low end. This value is one of the 3 blue user inputs (# of flutes,
diameter, and avg. chip thickness) in the spreadsheet. My understanding of
chip thickness is just the thickness of chip that is cut. I assume this
could be gathered imperically by picking up some chips and measuring the
thickness. Anyhow, to change it, just type in a new value over the old one
and the sheet will update with the new values.

I would probably go with the majority SFM (2 vs. mach handbook), but as
having no experience cutting stainless, I cannot offer a valuable opinion.
Perhaps someone with experience could comment.
