I've got aluminum forgings to machine with a countoured surface. The 2d pocket routine runs fast but it cuts too much air. What's the best way to rough the countoured surface to the flat with the holes? Naturally I'll need to run more pathes to get past the flat but I want to use an 1.250" dia. rougher/finisher to remove the most amout of material the fastest?
I get them from several sources. They come in different sizes and contours. PM for more info.

I don't understand why you're cutting a bunch of air with your 2d tool path unless you're cutting on multiple Z depths with the same full tool path.
Can you copy the geometry and then trim it up at the various Z levels you're going to cut. Trim away the portion that would be air cuts.
Without knowing how big the part is and what kind of a setup you've got, it's hard to say how big of a cutter to run.
PM me if you need help with the 2d geometry creation.
