Master Probe

Scott Brown
Good Afternoon

I have read a number of posts regarding probe calibration and using a Master probe to relate multiple probes. I have a few questions that I did not find the answers in the posts.
Question #1 - If you are using the Master probe for measurement does it affect the relationship of the other probes if you re-calibrate A0/B0 of the Master Probe after answering "N0" to the calibration sphere move. For example - Start of shift the Master probe is calibrated at A0 / B0 and you answer "Yes" the tooling sphere has moved. Now you open a program that uses the master probe for measurement. You want to perform a calibration on the angles that are used in the program. Perform a Marked Used which includes A0/B0. You answer "No" the tool has not moved and perform calibration. Is the relationship of the other probes and angles lost???

Question #2 - Is it necessary to calibrate Master Probe every time the machine is homed??

Thanks for your help

  • Question #2 - Is it necessary to calibrate Master Probe every time the machine is homed??


    I think machines are homed after the controller is restarted no? I don't have a big set up so I normally calibrate after the machine is restarted and homed. That is what I instruct the operators to do.

    I'm still thinking about your first question. I was always told try not to use the master probe for measurements. I would think no, the relationship between the other probes and angles is not lost as long as you answer "no the tool has not moved".
