Heres the deal.
Im trying to measure the ID and location of simple hole approximately 17mm in Dia. I want to scan it though.
1st: I created and auto feature of the circle by clicking on the CAD model.
The circle is perfect at this point. Exactly what I would expect from the CAD.
2nd: Measure the circle with the SP600 via touch points with the Auto Circle.
The circle is clearly off location in X by about 1mm and slightly large in D, but I've expected to see this also.
3rd: Create an alignment to the auto feature, and measured circle. The CAD model and the hole become realigned perfectly as expected.
4th: Using the Linear closed scan above I click on my starting point and the direction of the scan, then change the value in Z to match my depth I want to measure the hole (-0.5mm) at and this also levels my cut plane (0,0,1). After verifying that only the CAD surfaces that I want are selected (in this case the hole), I then click on the Generate command. The Demon shows 365 hits in the hole exactly were I want them.
5th: Verifing that the following settings have been selected, and I uncheck measure option. Then click create. The screen goes nuts for a second as it generates hits for the scan but then the scan command looks ok.
Linear Closed Scan Settings:
Direction 1 Tech: = Nullfilter
Exec Controls = Defined
Probe Comp = Checked
Nominals Method = Nominals
Tolerance = 0.100mm
Only Selected = Checked
Now heres where it goes wrong for me..
If I construct a circle before measuring the actual hole, the constructed circle turns out with the correct Theo data from the pre-measured Scan points.
But if I construct the circle after I execute the scan I get garbage Theos for my constructed circle. Actually the Theo appear "almost" perfect to the measured results (within a micron plus or minus).
Regardless, I spuradically get the "could not Find Nominals" error message box. Considering that Im working directly off the CAD model, and I dont want it to be looking for "new" nominals. I want it to use the original Theos which were created from the CAD model when I first created the scanned hole.
I also have Find Nominals turned off in the Setup options.
Both my Low Level Matrix and my Probe Calibration are setup and seem good. I dont believe these would have anything to do with my theo values changing anyway?
What else could I be missing? It clearly isnt working as I would have expected. I just got my new toy (the SP600) a couple of days ago, but I dont think its me this time.
Thanks in advance guys
