| Abstract | An uncertainty budget for measuring the roundness of high-quality parts using the reversal method has been developed. A systematic source of uncertainty due to the non-linear nature of the and operators has been experimentally verified and a simple method to remove the bias developed. The dominant source of uncertainty for the measurement of high-quality parts is the difficulty of realizing the correct measurand when the form of the part varies along the rotation axis. Example uncertainty budgets for both a steel ring and a glass hemisphere are presented. The expanded uncertainty (k = 2) for the out-of-roundness of the hemisphere is 4.0 nm. |
