I'm not super familiar with the 18T control but I had some thoughts on this. Using cutter comp is the way to go. You don't have to fudge numbers to get what you want. What is the radius of the insert you are using? Do you have the radius plugged into the R value on your tool offset page? Do you have the correct T value for the quadrant your cutting in? I don't see where you are calling the cutter comp in your program. Normally we use G41 for ID work and G42 for OD when working on the main spindle. This looks like your contouring an OD. I'd use a G42. As an example, if I were using a DNMG 432 insert to turn the OD I'd have .031 plugged into the T value on the offset page for tool 1 and T3 for the quadrant. I'd also call up my cutter comp after the face cut during the positioning of the tool prior to calling up the canned cycle. Remember to cancel the cutter comp before you call up your next tool.
