Auto calibrate

M1chaelx
Hey


i want to automatically calibrate my probe in one program for some time, is
this
possible and how.
  • The first step would be to search for the answer.
    The second step would be to look into the AutoCalibrate feature (which would require some searching)
    The third step might be to search here on the plethora of topics with the exact same name, construction, and general layout.
  • in reply to Kp61dude!
    See, that's excellent. Usually i end up posting a link to a search item I found; you posted the whole search!
    I like it. I'm gonna steal that idea...
  • Yep...easy. Use it every day...

  • You'll need to create a parameter set for your probe. Load your probe, start typing autocalibrate and it tab. edit the code to select your parameter set and then you can calibrate your probe automatically, sort of.

    You must keep in mind that if you have more probes, 1 must be the master probe to where you would say yes_man or yes_dcc to the parameter set. Once you can do this, you can get a little advanced and print the resutls and even have pcdmis repeat the autocal if std are not within acceptable limits.

    TIP: when posting code on the forum, type [_c_o_d_e_] (paste your program info here) [_/_c_o_d_e] delete the underscores when you try it.
  • Say I have a parameter set which was just calibrated. If run a program which includes a tip from that parameter set, and another tip that is not; should I expect measurement error between the 2 tips?
  • Say I have a parameter set which was just calibrated. If run a program which includes a tip from that parameter set, and another tip that is not; should I expect measurement error between the 2 tips?

    That depends on how you do the calibrations of the tips. When you answer "YES, the sphere has moved" the calibration chain is broken, and you have no correlation between tips calibrated before that moment, and tips calibrated after (unless you follow the "Master Tip" procedure to re-locate the datum sphere when it has moved).

    You can always verify your tips by measuring a sphere once with each tip, and compare the XYZ and DIAM - if they are not the same (within machine spec) your tips are not correlated.

    Depending on your CMM/controller, the relation may be broken if there is a machine stop/start and/or homing between the two calibrations.
  • I thought this was the board for answers before the question gets asked, not questions looking for answers...
