  • true position question

    When I report true position in Xact and compare to legacy my position is out of tolerance the same amount which is a crazy number....but when I report the location of the diameter i am within .0015 X Y.... is there a chance pcdmis is.... calculating position incorrectly because .050 seems a bit much.. Thank you

    Lets see some pics of these results, are your X and Y's the same? Blind leading the blind

      the x and y are the same when I report xact and legacy... but when use location they are very close..

      i dont know how to post pictures im sorry..

      In the past when I had this issue it was because of my alignment... in this instance i am confident it is not my alignment..

        What are your datums? Is your legacy alignment datums and the datums you define for Xact the same?

        Post some code?

                theres more but thats all the code up to my dcc alignment,,,, thank you for cleaning that up for me

                  cyl_datum_h, pln_datum_f and lin_datum_e have the same theo vector, and pln and cyl have very close theo coordinates.
                  Without seeing the print, I can be wrong, but I think it's strange.
                  I would check differences between datums references and alignment.

                      my part is basically a cross thats slanted..... DATUM H is the right side bore of the cross.... DATUM F is the face of DATUM H... and DATUM E is the other side of the cross through to datum H.....Hope this makes sense.....

                          hopefully this helps clarify...to show all the datums.... C and D are strange so I used the bore for C and constructed intersection points to construct datum D

                              How log is the bore for C ? Is that a casting ? If C is really short I would consider using the larger OD surface for leveling and then 0.000 on the bore for x -y or z. Depending on machine process I do that for a bunch of parts we do. Bore is really short be we do concentric bore on opposite end of part and then hold it from both ends, like turning between centers. I make a compound datum from both bores. Only 1 end is the print datum but its so short it alway told me my feaures along the length were" wandering" off the part. Indicator would tell me I am withing .0005. Change to this datum structure the CMM matched the indicator flawlessly. Yeah, I know the print says.....blah blah
