Hello
I need some advice on "deep pocket" milling in 6061.
The part got 50mm walls. We rough everything out with a long neck roughing endmill.
But what about the finish passes?
I can't use an endmill bigger than 14mm because of the corners (8mm radius). I don't want to use a 16mm one because it will chatter in corners.
Two tooling reps don't have a carbide endmill long enough to do the finish pass in one z height.
What I could do is finishing in multiple z depths but it will leaves lines I guess? No experience with it. Normally our parts aren't this high.
One tooling rep recommends a HSS-E-PM endmill for finishing in one pass. But how good will the HSS endmill hold up? Again no experience with HSS, since we always run carbide.
Any advice on this is appreciated
