摘要
本文对国际机械生产技术研究协会(CIRP)计量科技委员会统一文件中推荐的圆度误差的最小二乘圆参数算式提出了不同见解,推导出理论算式,并指出有限采样点不能唯一地确定截面圆度。
In this paper, the author points out some views different from the CIRP Measurement Committee of Science and Technology about the formulae for calculating the parameters of least square circle and presents the correct formulae. It shows that the roundness of a section can not be uniquely determined by sampling limited finite points.
