Gear manufacturing is a very tough manufacturing for me. I tried some operations. But I did not get a good result.
I only suggest you,5 axis streamline and tool axis 4 axis normal to part with rotation angle and projection method is normal to drive.Tool position is tanto. Also you could use generic motion tool path if you can.
I did not give you model, because result is not good.I did not love tool paths.But looks similar video.
