Condition-based quality maintenance in multi-process machining

In face of the demands of quality maintenance in machining process, aim at continuous change of the condition of complex multi-process machining, a concept of “Service-oriented machining process(SoMP)” is put forwarded in this paper. Quality maintenance in multi-process machining is taken as the service target. A framework of quality maintenance in process based on remote is established. On the basis of the framework, system architecture of quality maintenance oriented to remote service is constructed. In allusion to the degradation of service process capability, a flow of degradation evaluation of process capability for process stream is set up. It starts from requiring process condition information, through condition tracking, dynamic analysis and prediction of process condition, to realize decision-making of quality maintenance for service-oriented machining process (SoMP).
