Base alignment partially without probing (manual planar rotation and Z input)

[[Be...]]

Hello everyone,

I am looking for a way to avoid having to switch between our probe and visual system during the base alignment. For the planar rotation and Z-origin we currently are using our probe. For all other measurements we use the camera of our O-inspect. The planar rotation and Z-origin are not that critical, so in my view should not be measured each time, especially while using the auto run for multiple parts.

My goal is to measure the bottom plane once, save the position/orientation and then be able to recall this data into the base alignment during future measurements (among those also done with the auto run functionality). The other elements of the base alignment do need to run each time, so using ‘basealignmentname’(CNC) can’t help me as far as I can see.

I look forward to see what inventive tricks you guys can come up with. Keep in mind, I’m still just a novice trying to get a hang of using Calypso.

Measure the feature once, then under the "Nominal Definition" drop down in the feature, select "Actual to Nominal". Once the nominal values change to whatever was actually measured, select "Theoretical Feature" under the same drop down. Now when this feature is used in the base alignment(CNC), it won't measure anything because the values are already there (theoretical).

Note - I have no idea if this will work in your scenario so some tweaking or PCM may be required so use this information with caution.

Create a program for a part alignment as if it were a fixture. Load this alignment in your inspection plan. There are a plethora of ways you could accomplish this. It all depends on your end goal and specific use.

This got the result I was looking for, thanks!

Small note, as I did the "Actual to Nominal" step, it rounded the values. You can apparently avoid this by going to the Measurement plan editor feature > Units > Roundoff meas. for preset nominal value > set to 'off'

Wouldn't this overwrite/avoid the entire alignment, instead of just one of the translations/rotations?

You can load alignment into program - not just recall base alignment.
Then you can use theoretical element with loaded alignment to be used in base alignment, or measured elements can have new alignment using that theoretical element.
