  • Problem with the construction of a concentricity

    Good day to Y'all!!


    I hope you can help me.


    I have a request from a client to mesure a concentricity between to circles of a part. The thing is that i don't know how to constructed the dimension or if it's possible to do it so in PC-DMIS. In attach oe below i show what the client is demanding me.




    Thank's in advance.

    Attachment is not shown. So without seeing an example, I'd create a cylinder, as your datum, then create a circle. Measure concentricity of the circle against the cylinder.

      Sorry,


      Maybe now you can see the example.

        Just an interesting fact... Concentricity has been removed from the most recent version of ASME 8)

          The new Y14.5 will be missing CONCENTRICITY and SYMETRY. I think its out in a few months.?

            Antonio,
            Concentricity is always RFS and your example shows MMC.
            I would clarify with the client, I think TP is what they're looking for.

              Maybe it's an ISO drawing?

                Looks to be an ISO drawing.

                  As for ASME 2019 standard, if a drawing states to use 1994 or 2009, and they state to use concentricity, aren't we bound to use that standard? Or does the new standard override the old standard no matter what?

                    Bound by the standard referenced on the drawing.

                    This is one great benefit of ASME... Stated version sticks!

                    That is what I expected.

                  If its ISO drawing ask customer if you cant evelaute it as position Xactmeasure insteed of concentricity. if you realy want bonus for REF D its not possible to get bonus for REF D in concentricity.
                  See exampel. obs the Xactmeasure is not measured just constructed

                    Thank you Michael,


                    I'have already tried the position dimension and that really helps. But i wasn´t shore that i could use this. I will ask my client.

                    Thank all of you again.

                      Michael just one question,


                      how do you put the maximum material condition in diameter of 0.5 for the concentricity as your first example?

                        You must use the ISO standard iso1101.jpg
