Boring Radial Hole in Polar Coordinates

[Jlong59ND9]

I am trying to bore (2) holes on the outside of my part by using an end mill. My lathe does not have a y axis, so I plan to use polar coordinates and move in the X and Z to achieve this. I am having issues programming/posting this to achieve what I want in Fusion 360.

Any help is greatly appreciated and see an image of my part below:

Thanks

Not sure I understand.  Are you using a lathe or mill and what is the setup?

Sorry, I should have been more specific. 

I am using a 2 axis (X and Z) lathe. I have a 3/16" end mill mounted into a radial live tool on my turret. In a perfect world, I would just drill the holes with this radial live tool holder and the required drill, but I don't have the room on my turret for the different sized drills etc. as the spots are taken with other tools.

So, I would like to use this 3/16" end mill to bore the hole to both sizes and add the flat on the smaller hole. I don't have a y axis on my turret, so I think polar coordinates will have to be used to interpolate around the hole in X and Z.

Does that help clarify?

Its for the A axis but might be a good starting point
