Calibration question

Lets say for example, hexagon calibrated your cmm, and found that it is OOT. For example one of the axis is reading .00008 over the machine spec. And they say it may take thousands of dollars to bring in spec. What does it mean to you? Does it mean that they will put out of service sticker? Does it mean the machine must be in spec, even if most of your tollerances are +\_.01 , no less?

What would you do if it was up to you? Would you, hire Hexagon to tear apart the machine to rebuild it and bring it in spec? or would you still use it, since your tollerances are wide open, and .00008 wont affect your results much?

  • We have a few pieces (micrometer and a couple of calipers) that are "out of tolerance" but well within our specification. The calibration lab recognizes this and puts a "limited calibration" sticker on it. If questioned by an auditor, you just show the report that explains what's out and why it will not cause rejected material to be accepted. I have never had a non-conformance (major or minor) from an auditor using this practice.
