高能光源吸收器轮廓度误差评定方法研究
Study on the Evaluation Method of Profile Error of High Energy Light Source Absorber
摘要
Abstract
To study the method for evaluating the profile error of the photon absorber in the storage ring of high energy photon source,and select a suitable data registration method to achieve a high-precision solution for the profile error.The sampling point normalization method and the model matching method are used to process the measured data of 56 photon absorbors in coordinate measuring machining(CMM),which realizes the unification of design datum and measurement datum,eliminates the position error and obtains the profile error value ep.The reliability of the two methods is analyzed.The results show that the accuracy of the model matching method is better than that of the sampling point normalization method,and the worse the accuracy of the absorber,the greater the difference between the two methods.When the processing accuracy of the absorber is high,the fitting deviation between the measured and theoretical point sets is within 0.1 mm,and the difference of the contour value between the two methods is within 0.02 mm.关键词
