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
In Legacy Datum 1 shows a diameter size Datum 2 doesn't show anything, meaning Datum 2 is a plane. They are calling out
Good news if your callout is correct then they screwed up.
Sorry your new, let me be clearer. D1 stands for first Datum in the FCF, its a diameter, so it is leveling to a cylinder, D2 datum means it's rotating to a line or surface if you switch the 2. D1 would not show a plus or minus value or nominal, because it's leveling on a plane, your examples show the opposite.
That's even worse, because a circle represents a common center POINT, can't level to a POINT, at least with a cylinder it would be a common center LINE, at least you could level to a line, not the best, but you can.
