  • Difficulty understanding actual and theoretical values for newalignment

    Hi..I am new to PCDMIS...I did manual alignment of a part using 3 planes and also a DCC alignment too with 3 planes.I have to check the part for circle position and dimensions with respect to datum.I am getting different results for circle position when I check the same part next time.Circle dimensions are measured same..why this happens.
    Can any of you guys help me

    Dont know if this is the problem but, use the DCC alignment planes as your ref not the manual alignment planes.

      You need to post the code as there can be many reasons .

        Post some code. Sounds like an alignment issue.

            Alignment. Post relevant code.

              It has to be your alignment.

              If you're measuring a part that has 3 planes with an ABC datum structure, it is advisable to use the PRIMARY-SECONDAY-TERTIARY construction method. This will correlate the closest with results you would see on a surface plate.

              Once you post your code, we'll be able to dig into your specific issue. Until then all we can do is guess.
