P.S. Doing that with a very large ball end mill is a better choice. Looks like you might have used a flat endmill.

yep… Something like this…
Yup, used the Whiteside 1/4" Spiral up cut (RU2100)
I have the 1/8" ball end mill from the shop, but I need something larger for this or I’ll be here forever.
LOL I did a sign one time for a friend all 3d at 12" high and 24" wide, with some extremely fine detail, had to use a 1/16th in ball mill at like 2% stepover. I promise you could mill that cup with a human hair faster than I did that sign LOL. I had to pause it every so often and go take a break. I want to say just the finish pass alone was 14 hrs. It was crazy.

Actually how do I do that? Do I make a second tool with a lower stepover and use that for the final pass? I guess I would manually delete the “tool change”
Looks great! Min/maxing is the way to go. If it’s not a glass cannon, you have the wrong build… Wait, wrong topic…
Even 5% stepover with the peel pocket strategy leaves this little nub. Probably because it is a bull round nose bit?
Does that still happen when you use the 3D carving mode?
Did you tell it you were using a ball nosed mill for that or does it still say 0 for the edge radius?
Just using 2D now, would have to test 3D.
I did set the edge radius in Estlcam to 9.53mm (3/8")
That is a new one. I would try 3D waterline should do almost the same as peel.
Looks like 3D waterline is like the linear pocket.
I could just do linear pocket for the final pass.
Weird, normally that follows the contour down. Like the waterline of a draining bathtub.
Only in 3D mode. Not in 2d. It has no idea there is a contour at the bottom beyond his bit settings in 2d
That is my suggestion, 3D carve that with a mask to keep it in that area and 2D the rest. That will give the most control.

I just updated my drawing to be the 3/8" radius of the new bit I got. I want to try 3D with the 3/4" diameter round nose bit.
I am trying to balance the design vs what is feasible to make. I don’t need that exact curve.
I’ll share in the gallery soon. I got a completed one yesterday that looks sweet.
Actually used “parallel”. Linear plunges into the material and parallel peels in, then does a full depth pass. Since the previous pocket was a 30% stepover, it doesn’t seem like too much load.
This produced a nice flat bottom.
