I'll try to make you a drawing of what you need and post a pic later. One thing that you have to remember with Lathes is that your working in Diameters not Radii. So with that said everything in Z is Double in X.
Also you will need to use Tool Tip Compensation unless you want to spend wasted hours fudging around with your program to get the geometry on the part correct.
In the Tool Offset Geometry Page you will see X Z R T
X= Geometry Position part Center Line
Z= Geometry Position Face Z0
R= The Radius of the Tool Tip Insert ANSI CNMG432= .0312 Tip Radius
T= Tool Tip Designation 0-9 (for an O.D. turning tool this would be set to "3" and I.D. Boring Tool it will be set to "2") There should be a Chart in the Programming Manual
G42 is for O.D Turning Toward the Spindle
G41 is for I.D. Boring Toward the Spindle
Example a 1 inch diameter with a .1 45 Degree Chamfer is as follows.
O0001

G28U0W0M9
