Error Items Analysis of the Cantilever CMM with REVO Applied

Article Preview

Abstract:

Compared to the conventional CMM(coordinate measuring machine) with three orthogonal axes, the CCMM(Cantilever CMM) researched in this paper has two axes perpendicular to each other and one rotary axis. Hence, the error parameters in CCMM are also different from the 21 items geometrical errors in CMM. The application of REVO in CCMM makes a big difference compared with the application in CMM. This paper analyzes the error items existed and needed to be calibrated in CCMM and identifies the error parameters of REVO schematically, which lays a solid foundation for further research and application of REVO in non-orthogonal CMM.
