This paper deals with the uncertainty estimation of measurements performed on optical coordinate measuring machines (CMMs). Two different methods were used to assess the uncertainty of circle diameter measurements using an optical CMM: the sensitivity analysis developing an uncertainty budget and the substitution method based on measuring calibrated workpieces. Three holes with nominal diameter values in the range from 2 mm to 6 mm were measured on an optical CMM equipped with a CCD sensor and expanded measuring uncertainties were estimated to be in the range of 1-2 ìm.
