True Position in 3 axis???

1CMM4ME
Ok, I have read the post regarding this so called argument that my boss and I got into today. He told me that you cannot measure true position in 3 axis, as I told him he was wrong. I know it depends on the way the FCF calls it out, but I tried to explain to him that it is possible to measure TP in 3 axis.
I have seen the formulas, so I know it's possible. I just wish I could get one of you gurus to reply back explaining that it is possible and why. I see the picture but he does not. I do not like to get into pissing matches with upper management, but I have learned a h**ll of alot from you guys, and I know this is possible. So if one of you fine gentleman can back me up on this, I would very much appreciate it. Thank you very much.
Now I am going to get a cold beer.Smiley

  • John,
    The part is a square block with a counter bore in the middle of it. The drawing is asking position of the "central point " of the cylinder ( meaning center of x,y,z) of the cylinder to datums, a-b-c. A datum in x, b datum in y , and c datum in z from the bottom of the part. Basically it's a point that has been established within the cylinder with basic dimension to all 3 axis noted as datums. It only makes sense to me that if that centroid point has been given basic dimensions from 3 axis that are labled datums a-b-c-, that you should be able to calculate it as all 3.Confused
