摘要
JB/T 7557–1994《同轴度误差检测》在数据处理过程中遇到的minmax问题颇具典型性,其取用的计算方法在关键环节没有给出明确阐述,令人对其算法的合理性与计算结果的可靠性产生疑义,为此另辟路径寻找满足"最小区域"原则的合理算法,提高了计算精度,修正了该文献附录B算例中之11个截面圆计算结果,进而修正了同轴度误差的最终评定值.
The minmax in the data processing of Coaxial Error Detection（JB/T 7557-1994） is a typical problem.The reasonability of its algorithm and reliability of its calculating results were doubtful because many key steps of the calculating method adopted were not clearly expounded.Given this,a rational algorithm which fits with the ＂minimum area＂ principle was chosen to improve the calculating accuracy and correct 11 circular cross-section results in algorithm of Appendix B.Then,the final assessment of coaxial error was corrected.
