It's time for my yearly calibration on the Global 777 CMM. All calibrations up to this time have been done with the B89 ball bar and have been within the acceptable limit of Hexagon certification.
I understand that a B89 calibration is checking for repeatability and not actual length of the bar. The Koba bar or step gauge will check for actual length. What kind of calibration do most of you
have performed on your CMM and how would I know if my machine needed this type of calibration?
