Quality of machined products is often related to the final shapes of the manufactured surfaces. This paper presents a novel method for surface monitoring, which combines Gaussian processes to model the manufactured shape and multivariate control charting for monitoring the deviations of the actual surface from the in-control pattern. Regardless of the specific case study, the proposed approach is general and can be extended to deal with different kinds of surfaces or profiles.

Abstract
Quality of machined products is often related to the final shapes of the manufactured surfaces. This paper presents a novel method for surface monitoring, which combines Gaussian processes to model the manufactured shape and multivariate control charting for monitoring the deviations of the actual surface from the in-control pattern. Regardless of the specific case study, the proposed approach is general and can be extended to deal with different kinds of surfaces or profiles.File in questo prodotto:
