The depth and feed of any given cut will hinge a great deal on the power
and rigidity of the machine in question, but you can take this to the
bank:: stay away from large radius tools unless they are absolutely
necessary. Anything beyond 1/16" is asking for grief on light duty
machines, which would include the Clausing. Mind you, I'm thinking of
machines similar to a Mori-Seiki, Axelson or Monarch when I judge the
Clausing. I'm not implying it's not a decent machine. It is-----it's
just not heavy duty, and not well suited to running form tools.

I might suggest that you may be able to pull a cut of .100" depth per
side, with .010" feed when roughing, in steel. Could be wrong. All
depends on how tight the machine is, and if you have the horsepower, as I
stated. I can reduce 3" steel @ .200" per side, .012" feed, negative
rake, with my 3 hp Graziano Sag 12.

Your pretty much right on, I usually rough with my 5904 at .100" a side
and .006 or.008" feed, and while definitely working it isn't
uncomfortable. I've pushed this machine harder but you sorta get that
'don't turn your back on it' feeling.

The nature of the tool makes a huge difference. Are you using HSS? With
a proper chip breaker, that should be a nice cut, yielding a coiled chip, if
not broken. I've always accepted coils in lieu of breaking. They're much
safer to handle than strings, and are easy to clean up. Best part is, if
you're used to running negative rake at high speed, you don't get those
nasty blue chips that fly off the jaws and burn to your skin.
