Evaluation of Uncertainty in Flatness Measurement of Coordinate Measuring Machines Based on Monte Carlo

Abstract

Based on the measurement method of coordinate measuring machine flatness, establish a black box evaluation model for CMM flatness measurement uncertainty, and analyze the sources of each uncertainty. Combining measurement examples, this paper elaborates on the evaluation process of CMM flatness measurement uncertainty based on Monte Carlo, calculates the included interval and expanded uncertainty of CMM flatness, and provides reference for the evaluation of CMM flatness measurement uncertainty.
