| Abstract: | The measuring principle and the assessing method of the roundness errors with roundness meter are analyzed in brief. It is pointed out that the elimination of the eccentricity and the hamonic filtration are most important in the roundness data processing. A new method for calculating the roundness errors with FFT and IFFT is presented, in which data processing procedure is illustrated and experimented. The main advantage of this method lies in unifying measurement concepts, improving measuring efficiency and simlifying instruments design. |
