Description

This paper presents the technique to get circularity, eccetricity and its orientation of eccentric cam shaft by applying the iterative least-square method to measured data. At first, it is shown that the off-set error of probe is computed from data measured under the condition of eccentricity e≥1.5mm by means of the new technique. Although the circularity grows worse by the off-set error of probe, this circularity is corrected by using the technique to compensate the off-set error. On the other hand, it is made clear that the eccentricity and its orientation are precisely obtained by the iterative least-square method.
