I don't usually look at the probe calibration results because I don't really understand what I'm looking at. I'd really like to gain a firm understanding of the data and
what it should mean to me.
I've been digging through old threads, and I'm getting closer. What I
think I get is that StdDev is the standard deviation of single-point error of the measured sphere for each tip angle. (I was told by another inspector here that that number should be .0002 or less.) I also understand that the MEAS D determines the effective probe diameter for each tip, and is used for probe size compensation.
I don't fully understand the THEO/MEAS XYZ (where the THEO comes from, what the MEAS means), or what is a maximum permissible error. What do you guys look for when you read your calibration results? What do you hope to learn from the numbers? What do you consider to be a red flag?
Vinni is right, theo comes from the build (probe.dat). The meas is calculated from real offsets of theprobe from the theo and the difference from the "master probe" (which one you use the last time when you said "yes, the ball have changed")
