摘　要:通過分析目前同軸度誤差評定的方法及其不足，提出了一種基于MATLAB優(yōu)化工具箱的同軸度評定方法，把同軸度誤差評定轉(zhuǎn)化為圓度誤差評定，提高了運算速度和準(zhǔn)確度。并分析了產(chǎn)生同軸度誤差的因素提出了改進方法。[著者文摘]
New Coaxial Error Assessment Methods and Error AnalysisTian Shuyao Huang Fugui Hou XuefengTian Shuyao Huang Fugui Hou XuefengAbstract:This paper analyses the method of the coaxial error evaluation and its disadvantages, and advances a new coaxial evaluation method based on optimization of MATLAB toolbox. Then it turns the evaluation of the coaxial error into the evaluation of roundness error, results the improving with the speed and accuracy of calculation. Last, it analyses the factor which the coaxial error brings and gives the advanced methods.[著者文摘]
