【Abstract】 The paper introduces how to deal with the measured data of the circularity deviation withcomputers when there is’t the roundness measuring instruments. The principle is discussedand the mathematical models of the minimum square circle,the minimum circumcircle and themaximum incircle are given for evaluating roundness.更多还原
