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]
