Discusses the principle and method of measuring cylindricity errorwith 5-probes error separation technique.The error range of measuring is giventhrough complete analysing and estimating the uncertainty of measurement. Theanalysing method is helpful for amending and compensating the error of machines Iand it's of universal significance for other form error measurements and real application of the error separation technique.
