Overriding Hole Sizes in Reports

Our engineering staff prefers that I use gage pins to measure hole sizes instead of the result calculated by the CMM measurement. This is not a problem for a diameter size callout - I simply use a Keyed In Dimension and type in the result measured with a gage pin at that point in the report. The problem is when I have to report the True Position for the hole because then the measured hole diameter for the keyed in dimension doesn't match the measured hole diameter in the true position dimension - which uses the diameter calculated by the machine measurement - not the pin.

Is there any way to override the measured hole diameter in the True Position calculation so that it will use the number that I've inputted through a Keyed in Dimension?

This is how it would look in the report -



MEASUREMENT POINTS - MP06

MEASUREMENT POINTS - MP07
==========================
DIM MP07= TRUE POSITION OF CIRCLE MP_6 UNITS=MM

  • There are several ways to do this, but have you tried the other calculation methods Pcdmis uses for holes? Instead of using LEAST-SQUARES, try MAX_INSC, this will report the size of the largest stud that would fit within the measured data (ie the smallest hole).

    If that doesn't get it for you, you would then have to make generic circles, using the XYZIJK from the measured circle and the R (not D, but R!) from the keyin dimension.


    Yeah, I've tried the other calculation methods - these aren't reasonable people that I'm dealing with here.

    I will try it with the generic circles...
