Why is KinAiry superior to shooting a scale bar running a 2-face test
Two-face tests and shooting scale bars are helpful but are not fully comprehensive. There are many parameters within a laser tracker that can generate errors. The benefit of the NIST IR.8016 process is that it is a volumetric check of many of a tracker’s potential geometric error sources. To accomplish this, many components are manipulated during the test – the positions of the tracker relative to the KinAiry reference bar, the amount of vertical and horizontal angular movement, and the orientation of the reference bar. By following this short but rigorous process, potential tracker error sources are exposed.
Performing only a simple 2-face test or shooting a scale bar is not nearly as comprehensive as the IR.8016. Data captured in this manner may well miss several sources of tracker error. You can end up thinking your tracker is good even though there is an issue.
For more information on potential errors not seen with simpler tests, please refer to the NIST IR 8016 whitepaper, (September 2014), Tables 1-4 / Sensitivity Matrix.
