Re: Feed and Speed calculator, what the HECK?

James, that is great, thanks. Where did you get chip thickness and
what is that?
How do you change chip thickness in your spreadsheet?
For carbide cutters in stainless I looked up 275 sfpm in Mach Hand.
That gives closer to 5000 rpm. Still seems way to high for me.
The cimco software is great, thanks
I guess the real question is which surface speed to use.
