Abstract

This study considers the impact of surface quality (surface roughness) on estimating flatness error when measurements are performed using coordinate measuring machine (CMM). Flatness error is estimated using various association methods and various sample sizes, while the distribution of sample points is done randomly on a flatness feature using the random number generator in Matlab. ANOVA is used for determining the significance of differences between the observed groups. It has been determined that the estimate of flatness error is affected by the processing method, the number of sample points and associative method used, but not by surface roughness.
