Need Help!- G68 QUESTION

[Dennis H]

I was wondering if this is possible?I need to cut a .125" radius on the top of a circle in the YZ plane all the way around.The circle has a 45 degree taper to it,the top diameter is 2.549",the bottom diameter is 3.225".I am using a .25" ball end mill.I have the code for the radius, but cannot use G68 to rotate it.Is it possible to do so?

I can rotate the coordinates with no problem doing linear moves.

This moves the way I expect it to,but when I put in the circular interpolation it cuts the arc in the wrong direction.Any help would be appreciated thanks.
