Unfortunately, I don't think it'll be as simple as you may think.
First, will your A axis be continuously spinning, like a lathe? If so, then you'd probably only draw half of the outline. The problem, is that you'd need CAM software to properly calculate the offset of the tool as it travels along the profile. You also need to calculate roughing passes, as you won't be cutting this in one pass.
Now, I'm not aware of any CAM software out there that's designed to do this.
If the A axis will be moving by gcode, then the method I mentioned the other day would be a much easier option. Create a 3D model, and use a 4 axis CAM program like DeskProto to create the g-code.
