Help to cut a 3d path in a bushing

Post by megclay »

I would like to put a grease groove
on the inside of a bushing in a figure 8 pattern
using a Lollipop mill and Engraving to follow a 3d curve

cutter movements
-z down the center
-y to inside wall
follow path all around
y to center
z up

I got it to work
buy finishing each segment one at at time
with a v cutter and a lot of 3d modeling and trial and error
posting each than combining all in note pad
alot of manual work
what is the correct way
