True Position Out of Tolerance

VVPTD


​

Hello,

I am having trouble understanding how this TP callout can be out by so much. I attached a pic of what the report looks like and the code is shown below. Does anybody have any ideas? I have tried redoing the alignment but that did not work. The alignment code is also shown below. Datums are -A- is the bottom plane of the part, -B- is a center bore, -D- is another hole (See attached op sheet) Thanks in advance!!

  • Did you define datum A?

    If not do so and delete the output and redo it. Get rid of the #
  • sometimes the demon does this. delete the dimension and re dimension. if it persists then your alignment is messed up or you aren't defining the datums correctly. what does XACT measure tell you the measured value are?
  • in reply to YGOLORTEM
    I defined A as the bottom plane, I just didnt attach the code. I will try to rerun it without the #. Thank you!
  • in reply to BIGWIG7
    Thanks for the advice! I will redimension and rerun.
    The measured values of -B- are Ø.6145, -D- Ø.2055, and the TP is shown in the pic. I am not sure what would be throwing it off so much...
  • Remove the keyed in MMB values for datums B and D. The FCF on the drawing does not specify MMB values in brackets and the values you keyed in are the wrong values. Based on the values you keyed in, I assume you were thinking you needed to key in the nominal value for each datum, which is not the purpose of this field. Always leave these fields blank unless the MMB values are specified in the FCF on the drawing. Note: PC-DMIS calculates the MMB values automatically when the keyed in MMB field is blank. Make sure the datums referenced have to correct size tolerance values on the report tab for D2 and D3.

    dang I cant believe I didn't see that! I bet this fixes the problem.
  • in reply to Rob Jensen
    Hi, it it still measuring falsely even after removing the keyed in values. Any other ideas? Thanks!!
  • Datum D's tolerancezone is planar and seems to be at a ~45° angle. Is this really the intention?
  • Try under the advanced tab in exact measure, selecting "use current alignment" instead of Datum reference frame.
