利用最小外接圆法评定圆度误差

Minimum Circumscribed Circle Method for Evaluation of the Errors of the Circle Roundness

阐述了最小外接圆法求解圆度误差的基本思想,给出直线准则和三角形准则下圆度误差评定的代数判别方法.依据该方法可以设计圆度误差评定软件,从而实现三坐标测量数据的圆度误差评定.

This paper introduced a basic idea of using the minimum circumscribed circle for evaluating the errors of roundness,and also the algebraic method of judging the errors of roundness under the beeline and triangle rules. By this method, the software can be developed to evaluate the circle roundness, and realize the three coordinate measurement of the roundness.
