speed and feed (aluminum)

[balibalistic]

Hey guy's,

I've got a large aluminum plate on the way which i intend to use as a drill fixture plate.i simply want to remove about .020 from the top surface to insure it is 100% square to spindle for a project i have to do.

being a total newb i have been reading about speed/feed rates and get alot of mixed opinions.so what speed and feed should i run my 2" carbide indexable end mill at to get the smoothest finish possible?

Hey balibalistic,
You can use these calculators for speeds and feeds with the indexable endmill too.
This article explains the formulas.
These charts break it down.
Looks like 1500 rpm @ 18 IPM if it's a 4 tooth endmill gives the recommended .003 chip load per tooth.
Increase the rpm and you can increase the feedrate.
