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
Just another option, If you can't argue with the company that is checking this incorrectly, Then you will have to change your way of producing the part. You will have to drill the main hole and use a Pin to Level the part before drilling the outer holes, Because of the way they are calling it out, The outer holes now become more important to being parallel to datum B, then perpendicular To Datum A, that's what happens when you simply switch the 2 Datums.
Ok, but I have one problem
I write the correct program, measure the center hole (dat B) with three sample hits and use iterative alignment, but for this to be a cylinder I need to manually measure the hole twice at both levels, this will take much more time and my colleagues will not agree.
How much it will be correct to use alignment in a circle in manual mode and only in dcc to align with a cylinder ?
