Ideas for machining this?

With a slightly similar conundrum I cheated, drew it in Fusion 360, 3D printed it in PLA and had it lost wax cast. In my case it was the sloping sides of the teeth that caused machining difficulties.

Rotary table yes but no tilting equipment. I did think of propping the rotary table up but am not feeling too good right now so left it.

Rough mill and finish with file may be what i end up doing

Looking more closely at your model I am struggling a bit to understand the shape to be cut.  Does it have a focal point in the centre of the object.  I am thinking ball end mill for the step cutting do both ramps have the same profile to be cut ?

Yeah as I said I am struggling to describe it properly but at the lowest bit the tang will be 90 degrees but as the tang is pulled back by the cam the angle will change gradually by up to 12 degrees, hope that helps.
