We have had problems where one CMM has a tendency to lose what I want to think is probe calibration during the day. Me personally, I don't think it can happen without a software or hardware crash but I'm beginning to have my doubts.
I thought that I had brought this up another time but couldn't find anything in my searches this morning. We can be running multiple parts of one size (this has happened with more than just one program) and parts will start showing out of tolerance. We will rerun the parts that were good only to find them out of tolerance and when verified with another CMM (either another Hex or Renishaw CMM) all of the bad parts will check good. We can re-calibrate the probes on the CMM that was showing bad and then they are good.
We do weekly shutdown and restart on the PC and the controller and this is beginning to create a lot of issues with one CMM in particular. This has happened before and after we had the CMMs calibrated this year. Probe builds have been deleted and re-recreated at least twice this year and has not fixed this issue.
