Are you planning on making one or many? If it is many and the many is hundreds you should consider hand coding it. To make it simple you would need to do a minor redesign of the angle fillet between the boss and the flange; make this is radius fillet and then you can run around the boss with a big ball end.
A hand coded program will run faster than a CAM program and much smoother.
