Legacy TP - NoOK, Xact TP - OK

Recently we had a dispute, for many years we measured a part according to the program sent to us by our collegues from another country, I am forbidden to doubt their qualifications. They used an legacy method for measuring TP, everything was in order until we started having problems with the cnc producing this part, some holes went out of tolerance, for the sake of interest I tried to apply xact and for these measurements it is not ideal but in the tolerance zone, now we do not know what to do, because our parts do not pass through the old dimensions, but the repair service says that it cannot find the problem, I am still a beginner and do not want to go against great minds, but I just wonder how it would be more correct. Here measurements of the same part, and we use iterative alignment.
Have a great sunny weekend everyone Slight smile

  • In both cases A level, B origin, C one of the six holes to Y- according to drawing


    Are you sure about this? One of the holes PA should then be at zero deviation (in legacy evaluation). Could it be that a 2D-bestfit is done after the level/rotate alignment (as it should be done)?
    Xact does this for you, according to the datum structure.

    Possible to post the alignment code?
