Towards the control of product quality from the process deviation monitoring: Overview and investigation in automotive sector
Résumé
Key performances of industrial systems can be characterised by performances both related to the system itself but also the product/service it is delivering. It can be particularised in the manufacturing domain, by the performances related to the part manufactured (e.g. dimensional deviation, surface roughness) and to the machining centre (e.g. productivity, availability). The mastering of these two types of performances is nowadays mostly considerate separately, in the sense that current approaches lead to control product or machine performances mainly in an isolated way. Only few approaches try to take them into account jointly to permit to control performances of one thanks to the control of performances of the other and this all along the time. Thus a challenge in manufacturing is to be able to control part deviations from the mastering of the machining centre degradation. In that way, this paper is first proposing a review on current approaches able to support these two performance considerations and then to investigate scientifically, in the frame of automotive sector, a specific approach able to control part performances directly from machining centre performances
