Error Understanding in Computer Integrated Manufacturing Processes

Abstract

An increasing national priority on quality in product design and manufacturing requires significant advancement and new understanding to provide a supporting theoretical foundation and definitive science base. The effort to achieve needed productivity and performance advancement in contemporary computer integrated manufacturing embraces a continuum of disciplines that provides new levels of process performance. This includes a comprehensive definition of CADAM error accountability, feature design information at the process interface, apriori system linkages with aposteriori statistical process control, and integration of the advanced concepts of qualitative process theory with sensor fusion for complementing online domain knowledge. With online tracking of parameter variations a digital controller can then be adapted to maintain system error within a predetermined bound.
