How do I cut 3D egg shape?

[calebweller777]

You'll see in the pictures below that I can't seem to find the correct tool path to use when cutting this egg shape into the board. I'm using a half inch ball endmill and I don't have the option to change it. Is this going to be an issue? I just need to know how to cut it smoothly and in a timely fashion. Thanks!

Scallop or 3D Contour would be my best first attempts, closely followed by a Ramp strategy if the prior 2 options didn't yield what I was looking for

Typically, I would not rough with a ball end mill. Rough the hole out with a bull nose endmill and use an adaptive tool path leaving .005 and then use your ball endmill with a // tool path and .005 to .01 step over should work. If you have steep and shallow activated try that?

I would screen shot you something, but I am having issues with Fusion crashing right now. 

Also, it looks like what ever tool you picked to face your part has a corner radius and your step over is to large and leaving little islands on the face of your part.

I played around with the 3D contour settings and was able to get exactly what I needed! Thanks.
