  • Changing probes in a program

    Hey All
    Is it ok to change probes manually in a program?

    As long as you tell the CMM to select the new probe config you should be able to change it as often as you like... I always added a operator comment just before it and changed it when the operator comment came up, not sure why but always seemed to get a better reaction from the CMM when I did it.... I am assuming you are using a PAA connector or a TP20 though.

      What kind of probe have you got? Are you actually going to be unscrewing and re-screwing stuff?

        If you are talking TP20 stuff it's ok if you don't have to unscrew the tip back and forth. If you have no changer PCDMIS will ask you to remove and replace the module with the correct one before proceeding.

        I do not recommend unscrewing tips back and forth in between programs.
        I used to be high on life but I built up a tolerance.

          We have a TP200. I would thing unsrewing it would be a big no no :-)

            You can replace the module, but cannot unscrew the probe & change it without recalibrating

              I know you have to recalibrate it. I just ran a program where the ID is measured and true postion but the cbore is not. So then it is off to a difference CMM on the 2nd floor to measure the cbore seems a probe change in the program would be a good solution.

                You did not say you were just changing cmm's.......

                  Ya I know just walking up to the 2nd floor is much better then changing a probe, I must be lazy :-) and of course with my luck the probe on the other cmm will be the monster ball when I would need the 0.5 mm and of course it a manual calibration cmm as well :-) he!! it would proably be faster to write a new program

                    Consider an MCR20 Probe Changer? NICE!

                      Remember, you can NOT just buy a probe changer and expect it to work. You will have to PAY EXTRA for that option in Pcdmis and you will NOT be able to get that extra UNLESS you are up-to-date on your SMA.

                        Or consider a TP20 instead of the TP200.... are you using the TP200 for accuracy or just because you have it??

                          Ah if only we could, but seeing how we are closing it is a fight to get copier paper.

                            Well, if you have a modular type probe like a tp20 you can simply calibrate one tip on one module and then calibrate the other tip on another module being sure to calibrate A0B0 as well as any other angles you need and make sure to answer 'no' that the sphere hasn't moved.


                            If you will be unscrewing components, you will have to put the calibration for each tip in the program and not move the sphere while the program runs.

                              I had no idea it was an 'option' that uou had to pay for. WOW. PC does stand for Perfect Crime
