This is running on a VMC-10

What is the biggest amount to take from a facing mill?

I have a 3" dia with 4 insert. I need to remove 1.203 in the Z direction
Material is S7. The 3" covers the total part so the X & Y direction does not matter.
I want to remove as much as I can at one time. Right now I’m doing a peck depth of .075"
Rpm: 325
Feed rate 2.4 or .002 per flute.

Thanks
Chris
