I've got a part I'm running on a 5 axis hsk63a 40hp machine. It's about 6x6" cube of 1018. It ends up looking like a "T" when it's finish. It's clamped in a lang vise on the bottom of said "T", the specifics aren't super important other than to say it's not a super rigid setup, but for various tolerance call outs, it's exactly how it should be held. the bulk of the part and stock is up, over and outside the vise.
Now as it currently stands most of the roughing happens with the table at 90 degrees.
I'm using a 1/2 6 flute end mill
650sfm
1.1 axial
.09 radial
.004 chip.
11.8 cubes.
12 parts, before tool change.
This seems to be the sweet spot. I'm up from 10 percent at .007 chip. Far fewer entries, better tool life.
With that being said, I'm not usually one to try to save a couple bucks, but in this instance I feel like I've got some decent room for improvement. I'm wondering what kind of insert cutter might be available for a less stable setup. I don't have much experience with high feed mills, but I do suspect the considerable down force produced by a high feed cutter might be too great (remember part is at 90 degree) with a high feed capable of cutting a comparable MMR.
Thanks.
