Dimensional control strategy and products distortions identification

Abstract

Heat treatments could create local or global distortions on workpieces. Finishing operations, often costly, are then necessary to respect the required functional tolerances. In the long term, our objective is to optimize first, steel grade and heat treatment, then to adjust the numerical simulation models. In that way, the heat treatment distortions on C-ring test parts obtained for an ASCOMETAL steel grade, vertically gas quenched are qualified and quantified by a dimensional analysis. In this article, we focus on part measurement and data processing strategies. Then we present an approach to correlate the experimental results with simulations ones.
