i would like to use a 4th axis rotary to revolve this part while cutting a small groove with a ball end mill on a haas mill.
i tried the trace but the part remains stationary....
known issue: the sphere is hollow and not solid. the helix is a split in the spherical face, if i stitch and patch i lose the path 😞
1. i am not sure how to make a helix groove on the partial sphere ( should be solid ?)
2. i need a cam setup up to mill with 4th axis.
help please 🙂 cheers john
