Abstract

This paper describes the application of the random walk method for Bayesian inference to the identification of the process damping coefficient in milling. An analytical process damping algorithm is used to model the prior distribution of the stability boundary and it is updated using experimental results via Bayesian inference. The updated distribution of the stability boundary is used to determine the posterior process damping coefficient value. The method is validated by comparing the process damping posterior values to residual sum of squares results. A value of information approach for experimental test point selection is demonstrated which minimizes the number of experiments required for process damping coefficient identification.
