Rough shape
Use a surface rough contour on a true sphere to rough it out
and then it should be a facing pass on each flat. use the top face ( select solid by face) of the spigot as a check surface, and use values in the "Depths" area to control the Z level cutting zone
Faces
Your 5 axis post should be able to work out the angles required for each face
( T plane by solid face )
WCS is the setup view for each op, T & C plane selected by solid face
The operation on the flats would only need to be a 2D contour op, you may have to create a line across the face for each op
