Calibrating Probe Offset HELP!

afotion
So I just about had a heart attack today.

I'm wanting to calibrate my 5x Nikon Lens with my TP200 by1x30mmTip.

So I opened up the probe utility box

-Went to my Fixed 5x Lens tip, Calibrated to the Ring Gauge,Calibrated probe Offset-All went well with calibration, I closed out and went to select my TP200Tip
-Selected the TP200 tip and Saved my prior Tip calibration data as it asks, went to measure my tip had ring Gauge selected and right after is asked if the Calibration Tool had moved I hit NO and as soon as that happened the probe went directly down towards the table not even going towards the ring and snapped my tip! AngryAngryAngry I tried several times even after shutting down completley with the same result. Am I missing something? This was how I was instructed to Calibrate my Optics to Probe Offsets from the other programmer I work with and they have no idea what is wrong. Any ideas anyone?
  • You could calibrate the ring with the TP200 first, answer yes if it had move. Then calibrate optics, answer no. That's the method with a CMM-V, maybe it's not the same with fixed optics ?

    I'll have to try it the other way around then, thanks.

    I've taking class but could someone refresh my memory on exactly how to Calibrate your probe with your Lens the proper way so you can integrate both into a routine? That would be a huge help.
  • Maybe you can save the calibration in a set parameter, then recall it in an auto calibration ?

    If you want to run Fixed optics and a Touch Probe in a routine, how to go go about calibrating the optics to the probe otherwise known as a probe offset I believe. In other words there is a fixed offset if I measure a feature in DCC with a touch probe and I want to re-measure the same feature with vision, the system should know the vision probe is in a different area relative to the Touch Probe. My problem is when I integrate the two probes into a routine (10x Lens and Touch Probe Both Calibrated Seperatley) when it goes to run the Vision part of the routine, the lens goes to the same area but is roughly the distance between the probes away from the feature I am trying to measure.

    Help would be greatly appeciated!
    Thanks!

    Also if I am using a star probe do I need to do this offset for each probe or just #1? Ionly have a basic ring and sphre for calibration. The ring is not deep enough to calibrate the side tips of my star probe on it.

    The way I do it is to Calibrate my optic first to the ring gage. When it asks if the fixture has moved I hit "YES" then it does the MAN+DCC. I close out the calibration probe box. Select my probe tip, calibrate to the ring gage, but I do the MAN+DCC (not the DCC+DCC), so then when it asks me if the fixture has moved, I select "NO", then it asks for a manual hit so far down from the center of the ring gage.

    Try doing the MAN+DCC for manual calibration like that.
  • The question whether the fixture has moved will have two different results. Yes its moved will update the location of the calibration artifact whether the ring or sphere. No it hasn't moved will update the probe file from the last known location of the calibration artifact.

    On a vision system always measure the ring first with vision and always say YES its moved. The vision probe is the Master that everything else is offset back to. This will locate the ring in the measurement range. Your vision probe should always have a TIP location of 0,0,#. If X and Y are not 0 then someone answered NO at some point.

    Then choose a touch probe tip to be the secondary master. Measure TIP1 only on the Cal Sphere and answer YES. This will update the probe radius but will not update the probe location. Then calibrate the same tip on the ring gage and answer NO. This will update the probe location relative to the camera. If it is the first time you have ever measured the offset always use MAN+DCC. The manual hit is straight down about 5 mm from the inside diameter at 6 O'Clock. If you have done the offset before and know its close then you can run DCC.

    Then if using multiple probes or star probes, go back to the cal sphere with the same TIP1 and answer YES its moved, this now updates the location of sphere with the corrected offset of TIP1 to the vision probe. All other tips can now be calibrated back to the cal sphere and answered NO like a normal CMM.

    Hopefully this makes sense.
  • Thanks BuckB!

    This makes perfect sense. I eventually got it figured out. I am constantly making routines with both Vision and Probe features so it helps having to do it over and over again Sunglasses.

    Practice makes perfect!

    Thanks for the help!
