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 -

  • OK, I moved this to the Portable section.

    I still recommend that you should measure some diameters on a ring gage and seek techniques to improve accuracy with a Portable arm.


    If I get a chance, I will snap a couple photos of parts I am working with - some are cast aluminum with a parting line (and flash) through the middle of the holes and others are 6mm thick parts stamped for cold rolled steel. Accuracy of a diameter on a ring gage is a whole different story than real world application - pin gages have always caused me less of a headache due to the fact that measured results with a pin are highly repeatable - either the pin goes through the hole or it doesn't. I've had good luck with the diameters on thin stamped parts (1.0mm or less) with our DCC machine. The Faro arm with this other crap? Not so much...
