Once you have the speed (RPM) and feed (IPM) based on your material and tool then you find out what depth of cut you have the power for. If you have a large commercial scale VMC you might be able to drive a cutter with a depth of cut equal to the cutter diameter. If you are restricted to 1 or 2 horsepower you may need to limit your depth of cut to only 10% of the cutter diameter. It also depends on the width of engagement of the cutter, are you cutting full width or only 20% of the cutter width. And do you have no coolant, mist coolant or flood coolant. All these come into play and you need to do some experimenting.
An open mind is a virtue...so long as all the common sense has not leaked out.
