Vision/Tactile Mix for Alignments

Good Morning All,

Is it acceptable to use the touch probe for a manual alignment and then use the Vision probe for the Dcc alignment?

OR

Use both use touch probe and Vision for manual and touch and vision for Dcc alignment?

Thanks.
  • I used the touch probe for the manual alignment and a rough dcc alignment then the vision for the final dcc alignment.
  • I don't see why not. They are all linked together through calibration.
  • Thanks for the info.

    We've had our optiv for over a year in cell that only produced 1 part. I was never able to get the vision to work on it so it was inspected 100% with the touch probe. We've replaced the optiv with an Equator and I'm trying to do more with our optiv.

    So in the area where they want to move the optiv to, most of the parts we want to inspect have more features that will use the touch probe(s) and maybe 1 or 2 features with vision.

    I'm in the middle of ordering supplies to make fixtures for these parts.

    That's true, but some checks on features which are "measurable" by both "probes" is usefull, interesting, and sometimes surprising... !

    Agreed! Vision can be picky, even with filters applied. It can make measurements different between the two.
  • I have an Optiv 443, and this is a common practice of mine.

    All our parts are cylindrical, so I chuck them in a rotary. I'll measure the outer diameter, the face, and points in a notch (if applicable) manually, then DCC those points out.
    I'll take all of the notch depth measurements necessary with the touch probe, then switch to the camera. I use the touch probe alignments to get a general location, and then align to the notches themselves.
    There are two alignment systems going on, but they work in tandem to take the points. At the end of the program is the fun math that makes it all come together.

    Of course you can only do this if you use the camera as your master probe during calibration...

    On a side note, everyone's right: measurements with Vision can be interesting. If there is anything on the part, perhaps even a spec of dust, it can throw off a measurement in a way that would not affect a touch probe. Be on the lookout!
