Uncertainty Evaluation of CMM for End Distance Measurement
摘要
Abstract
A complete uncertainty evaluation process of end distance measurement by CMM was presented. To begin with, the major sources of uncertainty, which would influence measurement results, were found out after analyzing,then, a general mathematic model of end distance measurement was established. Furthermore,Monte Carlo method(MCM) was used,and the uncertainty of the measured quantity was obtained. The complete results were given out,so the application value of CMM was enhanced. Moreover,seen from the evaluation example, the results of uncertainty evaluation obtained from MCM method and from the method provided by Guide to the Expression of Uncertainty in Meas-urement(GUM) method were compared,the comparison result indicates that the mathematic model is feasible,and MCM method to evaluate uncertainty is easy and efficient.关键词
