I have a funnel that I am cutting, 2" at the top, down to 3/8" bore at the bottom, 45 degree angle.
I tried with a 1/4" ball mill, but material has to flow down the funnel and surface finish has waves even with 0.020" step down.
I thought about running a 45 deg insert chamfer mill down it, single insert Iscar with a .25" center. I just have not figured out how to set the boundaries in Fusion360 as it wants to make a flat spot in the bottom. Its granular material that has very small light grains.
Any recommendations or ideas?
Drill 3/8 all the way through
1/4 Rougher
45 degree chamfer mill
1/4 ball mill to round off the transition down the hole
