Volume-wise, of course.
Opinions?

I read some time ago somewhere that it was drilling.

This surprised me, as I thought the drill point, being essentially zero sfm, would act as a limiting factor.
Intuitively I figgered it would be lathe turning, as the tool is moving along a large surface, so chip removal is almost a
non-issue, and coolant is "more effective" than it would be on a buried cutter, and here the tool is essentially never buried,
etc.

But mebbe it could be something like a large-kerf circular saw blade?
Mebbe a saw blade moving along like a Dumont grinder on a lathe??




The machine with the most HP.

I have a 30 hp swing grinder that will chew off metal as fast as most any drill or milling machine.

The fastest metal removal rate in a shop I worked in was also a grinder, a 200 hp Blanchard!
