I'm having trouble getting a decent surface finish when milling an elliptical pocket using a "Super" Mini Mill.
The side wall of the pocket looks faceted instead of being smooth. The same machine cuts circular pockets of all sizes just fine.
We've had the same problem with other Haas mills in the past, but changing parameter 191 to the finest finish has fixed the problem. On this machine (2005 vintage) though, I can't find a parameter 191 at all.
I've set my CAM software to the tightest tolerance and slowed the feed way down, but neither seems to help much.
Any ideas?
