Autocalibration Calibration Sphere

HunterS1103
Hello All,

I'm not sure if this is a common thing but i have an auto calibration program I set up to calibrate all our angles at once with. We have multiple calibration spheres that we use, for example when one is out to be certified by a 3rd party we will switch to other one. etc. my question is because I noticed that PC-DMIS defaults to the most recent Calibration sphere used when running the program. Is there a piece of code i can add to the routine to tell it what sphere is being used so it doesn't use the incorrect shank vector or sphere diameter?

thanks in advanced

    I would like to know how it's done as well
  • You would need to create parameter sets. I am not sure if this could be done all in one program and with variables, you can pick which parameter to use based on the sphere. But I would think you could have multiple programs, in which the parameters are already built in, that you would run the program for which sphere you have on the table.

    I messaged the guy at hexagon who trained me and he told me about doing a comment to select the sphere and make an assign based off the chosen key in. not sure if that helps or makes sense to anyone else who reads?
  • You would create a parameter set for saying yes the sphere has moved that you measure both spheres with auto calibrate statements.
    So Parameter set 1 for your gold probe would calibrate one sphere then parameter set 2 would calibrate the second sphere.
    Then you have 2 auto calibrate statements in your program referencing each of those parameter sets you created for them both saying yes the sphere has moved. Then the rest of the auto calibrate statements would use parameter sets that have the correct sphere selected inside them.
    Someone else will explain it better, I'm on site and cannot put a good example up.
  • Don't think you can directly assign calibration tool variable assignments. The calibration tool is selected in the probes menu and saved as part of the parameter set. There's nothing (that I can see, I might be blind!) in the calibration code block that reference the calibration tool that you can variablize (not a word, but should be!).

    Parameter sets, however can reference variables. So go to your probe menu and create a parameter set for each artifact, then in your program, set up some prompts to choose which artifact, then use some if statements to
    assign/V1 = "artifact1_all_tips"
    or assignv1 = "artifact50_all_tips"
    etc.

    Then set your calibration codes to have PARAMETER SET = V1
    and depending on your operator prompts, the calibration will select the assigned parameter sets.
