The measurement method of the global sizes of cylindrical parts based on Talyrond 585LT and the standard ring was proposed. The changing processes from the roundness profiles measured by Talyrond 585LT to the actual roundness profiles was studied for holes and shafts, respectively. The evaluation models of the least-squares diameter, minimum circumscribed diameter, maximum inscribed diameter and minimax diameter of cylindrical parts were given. The roundness profiles of two holes and two shafts were extracted and changed into their corresponding actual roundness profiles. Their global sizes were evaluated, and their measurement uncertainties were analyzed and estimated. The analysis and experiment results showed that the above measuring method can meet the measurement need of the global sizes of cylindrical parts for implementation of ISO 14405-1 in the manufacturing industry.
