How to mill a moineau rotor on a 4th axis

As I wanted to make a Moineau Pump for a clay-extruder or pellet extruder, I managed to make the design.(see attachement) in Fusion360.

But I'm struggling with the CAM part.

I have a CNC Mill with 4th axis, controlled via MACH3. So in one way or another it should be possible. Walking to the different posts, and videos it seems not that simple.

 

In the attached file you can see my setup, and 2 contour trials., but I miss the indexing part, and cannot find how to add that

 

Does someone have a better idea how to machine this rotor?
