STUDY ON EVALUATING THE ERROR OF ROUNDNESS BY LEAST-SQUARE METHOD |
| |
| Abstract: | This paper discribs the theory of evaluating the error of roundness by least-square method as well as the means of measuring the eiror of roundness in cylindrical parts though this theoiy This method can be realized by :he loundness instruments of aveiage accuracy instead of those of. high accuiacy, which are expensive. |
