Abstract: The mathematical formulas for roundness measurement has been descussed firstly based on the tri-probe error separation technique.Then the slideaverage method and digital filtering method employed in the data processing were discussed, these methods can effectiveoy control the interference signal and mise the signal/noise ratio.It is examined exeperimentally that the accuracy of roundness measurementcan be remarkablely improval with these methlods.
