So I have always been a fan of 3 flute tools in aluminum. They seem to have a little better rigidity than 2 flute, lower chipload at same feeds, plus they can be variable pitch, etc...
But when it comes to ball endmills, it's a little harder to find 3 flute tools. In fact, most of the really high performance stuff seems to be 2 flute. My thoughts is that if we go with 2 flutes, we are going to have to feed 50% lower. Am I missing something there?
Obviously the question is for doing tilted work, or work on the sides of the ball, since when we're dragging the center across a surface the SFM is basically zero anyways and the thing is just scraping it's way through.
