Abstract
According to the measurement method of cylindricity based on coordinate measuring machine (CMM), establish a black box evaluation model for the uncertainty of CMM cylindricity measurement, and analyze the sources of various uncertainties. Based on measurement examples, this paper elaborates on the evaluation process of cylindricity measurement uncertainty based on CMM, calculates the extended uncertainty based on CMM, and provides reference for the evaluation of cylindricity measurement uncertainty in CMM.
