Determination of measurement uncertainty on coordinate measurement machines by measurement decomposition and utilization of canonical artifacts

PDF Version Also Available for Download.

Description

The requirement for primary-level calibration of complex forms, e.g., gear profiles, has led to development of a method for quantifying the measurement uncertainty on the artifact being calibrated that does not rely on a transfer comparison. This method, developed jointly by National Institute of Standards and Technology (NIST) and Oak Ridge Metrology Center (ORMC) personnel, consists of breaking down the measurement method into simpler components and quantifying these components using generally accepted artifacts with low uncertainties (gage blocks, ring gages, spheres, etc.). Once quantified, these components are added vectorially according to NIST Technical Note 1297, 1994 Edition. Verification of this ... continued below
