Interpolation Turning
Unfortunately, there is no great out of the box solution for something like this in FeatureCAM. At least as far as I'm aware.
There is a turning head UDF in the default add-in library that will allow you to program a non interpolating version of this with a turning head.
That being said, I do think this is hackable. Off the top of my head, doing a side feature that only constists of a finish pass, and then checking 'helical side finish' would get you the correct interpolation path that you are going for. At that point, I would think you could hack something in the post to put out the correct corresponding spindle rotations to go along with that helical side finish toolpath.
The TL;DR is that there is not an easy way to do this in FC, but like just about anything, you should be able to cobble together a solution by getting a bit creative both in FC and in the post.
