CMM Health

Good Afternoon Everyone,

We are starting a CMM health initiative to help trust the CMMs. As of right now, operators can only run parts and the probe calibration program. Management is looking into something like check an artifact of known size weekly or even daily. I have (4) 454 SFs with (3) with manual heads and (1) with an indexing head, (3) Tigos with fixed analog heads, and (1) 7.10.7 Sf with an indexing head.

What kind of artifacts do you all check on a regular basis for CMM confidence? Rings gages? Gage blocks? An actual machine'd part? If its a machine'd part, do you check on 1 CMM to compare to other CMMs? OR does the human check it with hand tools and then looks for correlation? I know Hexagon has the swift check thing but I think its only for indexing heads so it won't work with all my CMMs.

Any advice? Thanks.
