Information-based Manufacturing for Selective Assembly via a Coordinated Statistical Tolerancing and Spc Model
Aimed at overcoming the disadvantages of traditional selective assembly and improving the manufacturing processes of mating parts, a new approach of information-based manufacturing for the mating parts of selective assembly via a coordinated statistical tolerancing (ST) and SPC model is presented. On the basis of studies on quality indices and process capability index (PCI), particularly, the m...
متن کاملInertial tolerancing and capability indices in an assembly production
RÉSUMÉ. Le tolérancement traditionnel considère la conformité d’un lot lorsque le lot de production satisfait les spécifications. La caractéristique est considérée pour elle-même mais pas en fonction de son incidence dans l’assemblage dont elle fait partie. Le tolérancement inertiel propose une autre alternative de tolérancement afin de garantir l’assemblage final. L’inertie I= δ + σ n’est pas ...
متن کاملEconomic design of the integrated multivariate EPC and multivariate SPC charts
The goal of engineering process control (EPC) is to minimize variability by adjusting some manipulative process variables. The goal of statistical process control (SPC) is to reduce variability by monitoring and eliminating assignable causes of variation. As suggested by Box and Kramer and others, it is possible to reduce both special cause and common cause variations by integrating EPC and SPC...
متن کاملInterest of the Inertial Tolerancing Method in the Case of Watch Making Micro Assembly
A mechanical part to tolerance is traditionally expressed as a [Min Max] interval which allows the definition of the conformity of the characteristic. Inertial tolerancing offers a new point of view of the conformity based on the mean square deviation to the target. This article demonstrates the efficiency of inertial tolerancing and proposes a comparison with the traditional tolerancing method...
متن کاملA Comparison Study of Distribution-Free Multivariate SPC Methods for Multimode Data
The data-rich environments of industrial applications lead to large amounts of correlated quality characteristics that are monitored using Multivariate Statistical Process Control (MSPC) tools. These variables usually represent heterogeneous quantities that originate from one or multiple sensors and are acquired with different sampling parameters. In this framework, any assumptions relative to ...
