Kriging‐based sequential inspection plans for coordinate measuring machines

Abstract

Abstract Kriging models have been extensively used to predict spatial data in geostatistics and, more recently, to approximate the output of deterministic simulation. This paper presents a novel application of kriging in the field of industrial metrology. Exploiting the recognized predictive capability of kriging models, we use them to drive the online construction of sequential plans for inspecting industrial parts on coordinate measuring machines. These machines are universally adopted to check the compliance of parts to dimensional and geometric specifications. In two analyzed case studies kriging‐based inspection plans outperform fixed‐sample plans widespread in industry. Copyright © 2008 John Wiley & Sons, Ltd.
