Worst use for a CMM?

OK hopefully this doesn't apply to everywhere but the engineers here seem to think that anything that needs measuring must automatically go on a CMM.... It has annoyed me since I started but most of the time I can see at least a little semblance of logic behind their thinking.


That is until now.......... We have a distance to measure (the height of an insert), now with a depth mic this could be checked within 30 seconds but let's be generous and include the time for me to go into my toolbox and get my mic, so we'll call it 2 minutes. Lovely quick turnaround everyone is happy....... Nope instead it MUST be measured on the CMM (which is running at max capacity and is looking like a 1.5-2 week lead time until I can squeeze it in).

Now I've argued every which way possible that it's a waste of time and the parts have been sitting on my shelf for a few days now and I have admitted defeat, but it got me wondering!

What is the worst thing you guys/girls have had to measure on a CMM?

If this gets no replies my faith in the world may be restored a little but if this goes the way I think it will at least I'll know I'm not the only one suffering and crying into my pillow at night.

  • For this sort of thing I just edit the measured values and regenerate the report... hate to say faking it but at times I nudge a report into spec.
    1) Edit the features theoretical value to be what you want the report to read
    2) When prompted tell it yes you want to change measured values
    3) Next it will prompt if you wish to change nominal on related dimensions, say no.
    4) Refresh and print the report you want to see
  • I've had times where I check it once and its good and other times I have checked 20 times and still cant good readings. Feels all kinds shady doing it.

    On the other hand I do nudge the numbers for Gage R and R to save me from redoing those....
