10:1 Rule - What spec do you use?

There's been some debate here about what the CMM is capable of measuring to when it comes to the 10:1 rule. Obviously we can change the resolution on the dimensions we want reported way out. What number do you guys reference for this?

  • Josh,

    Here is a copy of the cert that I am referencing. This is from Hexagon Tech K. T. that was here in July 2015. So what I attached was listed as the volumetric performance, measurement uncertainty. There is also a page that lists Repeatability, Measurement uncertainty but that shows Uncertainty at 0.029 um, but also lists each individual axis X (0.45 um) Y (0.55 um) Z (0.37 um). Is that what you were referring to instead of volumetric uncertainty?
