Running a part on our VF1 mill that we have run several times before. When the part is loaded on to the arbor to drill & tap 3 holes, the holes check 'out of position' on our CMM and the arbor itself does not retain it's zero reference (last time it was .020 off). My initial thought is the Arbor needs to be PM'd. One of my esteemed colleague's suggested checking the program to make sure it wasn't missing code that might rectify the problem. Any help or direction is appreciated.

Take a picture of the setup (or even a shitty hand drawn sketch will help), label everything and restate your question using those labels. Tell us how you are setting the work offset for everything.
Also, if you think the code may be at fault, post the program here. Not a snippet, the whole program.
Trying to attach a picture. Not sure it's working. When using MDI, we can get the fixture to return to A0. every time. When we run a program (have tried to different programs) it loses the zero in A. Since we have run these parts in the past without issue, I'm thinking the issue is with the fixture itself.
Sounds like your fixture work offset isnt set correctly.

What Delw said. What do you type in MDI? Let’s see the program too.
This is the section of program with the center drill and drill:

Do you have a value in your work offset for G56 A?

Do you jog your A to get the fixture flat? If so, the machine position for A needs to be set in your work offset for G56 A.
Thats your problem.
zero fixture. highlight g56 in your fixture offset page. hit the button on the left that says "part zero set"
make sure you are in your g56 and also make sure you highlight the A tab on the G56 line. so nothing else changes.
when you hit part zero set(which is under the F keys) you will see your A fixture number changed. NOW the fixture is "ZERO" for that particular work offset.( it always should read something)
