Hi guys I was just wondering how often you calibrate your probes? I have 4 cmm's (2 sheffields) (1 B&S) and (1 LK.) running 3.7 mr2 on all machines, Tool changers on all of them. We run layout on all 3 shifts. Right now we calibrate them every morning, once a day. The reason Im asking is because the other day I was checking a part and the probe that I was using lost its calibration in the 90-180 angle. Everything in that angle checked bad but all the other angles that was used in the program for the part checked good. I rehomed & recalibrated all probes in the tool changer then everything on the part was good. So now im wondering how often other folks calibrate.
