The authors have developed the algorithm to get the circularity of largely eccentric cylinder by means of the Iterative least square method. In this paper, it is tried to apply this method to the evaluation of cylindricity and the accuracy of related features for largely eccentric crank shaft.The related features mean the position, the parallelism, the total runout and so on. As the first step, the new technique is developed to get the form errors and the cylindricity, one of single features, for a crank shaft. Although the measuring accuracy of form errors is obtained in the order of 0.1μm by the instrument for measurement of radius deviation from rotating table center, it is revealed that the accuracy falls depending on the bending deformation of a contact probe produced by the friction force between specimen surface and probe tip.
