  • GD&T Z DELTA Between 2 Points

    I do not have a GD&T Book. I have a print here, asking for Z DELTA between 2 Points on a curved plane. Its been awhile, I believe this to be the Z Distance betweent the points. And if it is, can I do just a distance between them or do I have to zero one of them out? I know it the same thing, Just like to know what the book says. Or am I totally off base, and need to do something else?

    Is there GD&T on the net? I can't find it.

    Canadian John,

    Its a SUV Roof Panel, This is a dumb question. I know what I have to do, but maybe you can give me a out. The Z Delta, ya think it in da free state condition, not restrained?

      Paul,

      I just went through my GD&T books and I didn't see anything about Z-Delta. Could it be called something else. Could it be profile?

        Does the print specify restrained?? Also, I agree with TRD, it is not GD&T. They are looking to control the form of the panel at various increments. I've seen this on some of the ducting we supply. An "X" tolerance at a "Z" coordinate.

        When in doubt, post code. A second set of eyes might see something you missed.

          Here is just on section of the print. I believe this has something to do with where the robot will grab it and where the robot will weld it. The SQE will be on vacation until friday. Thanks for any input.

          Its the free state thing I am worried about. And it does not say to check restrained nore not restrained.

            the difference in Z between the two points.

            (It's ok to proceed, unless you are inspecting this in China, then you must stop, it is not in a free state.)

              I concur, Z difference.

              (China, free state, Now that is funny!!)

                  So, if I understand this correctly. Here I can check it free state. Their if I want to check it, I may have to find someone to stand in front of a Tank first.

                      IF you're checking Profile of Surface,This Delta Z distance will control the Location of your points,Since Profile of a surface will control Form Y Location.
                      anda Gd &t Book does not show Delta.
