Single Point Articulation Metrology Test for a Portable Coordinate Measuring Machine

A Portable Coordinate Measuring Machine used in precision measurement has complex physical structure built than conventional coordinate measuring machine. The operating environment in which it is being used experiences many limitations due to varying operator perception skills, probing practices, cyclic changes in temperatures and other factors. The single point articulation test is a quick test used to analyse the articulated arms performance capability to locate the point precisely. This paper describes the results of interim check process which is directed by ISO 10360-12 for six kinematic nests with touch probing method of coordinate metrology.
