Among the projects supported by the cluster is inertial tolerancing, a new approach in evaluating the quality of machined parts. Based on the Taguchi loss function, inertia is defined by its deviation from its target. Inertial tolerancing is a research-and-development program supported by the cluster for its member companies. It is led by a research team from the Symme Laboratory of the University of Savoie and the CTDEC ("Centre Technique du Decolletage"). The publication of the French standard NFX 04-008 demonstrates the relevance of topics covered by the cluster.
