You all have seen the super high feed rates of roughing aluminum in a machining center, and I'm sure some of you are doing it in your shops. My question is, what kind of end mills are they using? I'm talking about when they're running at 100+ inches per minute. I've seen 3 flute carbides being used for this but are there certain degrees of helixes you should use to accomplish these types of feed rates?
