  • Multiple Tip Calibration

    I've been browsing this forum the last couple of days trying to understand how to properly calibrate multiple tips. You guys have helped me a lot, but I still have a couple of questions. I understand to then say 'Yes' to the sphere has moved question, then calibrate your master tip at A0B0. I also understand to say 'No' to the sphere has moved question on all of the other tips to build a relationship between all of the probes. If I understand things correctly, you want to calibrate all the tips at A0B0 first, then the other angles. What I am confused about is if you need to add a new angle after calibration. I've seen posts that say that you can just calibrate that angle without breaking the relationships between the probes, and without having to re-calibrate all of the other tips and angles. We always take our sphere off the table after calibration, because it's in the way. I'm assuming I have to say the sphere has moved. Do I re-calibrate the master at A0B0, then calibrate my new angle? Do I have to re-calibrate the master, then calibrate the A0B0 of the tip I'm adding an angle to, and then calibrate the new angle? Any help would be greatly appreciated.

    Yes. That option.

      Thanks for the quick response NinjaBadger. I figured it was simple, I just didn't want to break the relationship with the other tips.

        No problem - T1A0B0 is your link. Always define sphere with that and you'll have no problems.

          On a similar vein,I regularly validate our fixtures,but very rarely use any other angles on the probe head other than A0 B0,recently I've had cause to use A90 B90 to check some bushes,but the
          result is giving me concern,one axis was reporting 1,00mm out in the plane,but when I reverted back to A0 B0 to check a point on the same bush it had a zero result.There has been a few collisions in the past
          and was wondering if the 'Knuckle' could be affected? any suggestions would be grateful

            Have you recalibrated that angle recently ? IF you have and you are seeing that kind of error....What size ruby ?

              1mm sounds suspect, if it's a 2mm tip then it's probably a workplane issue, but this would usually only affect lines, not points?

                Sounds that you have a 4mm tip but you have It built as an 2mm tip

                  Even if that was the case the qualification should have taken care of it
