Operations of an industrial product service system based on machine tool at user factory

Industrial product service system (iPSS) are paid more and more attention due to its roles in driving the win-win manner for environment and economy. This paper presents and clarifies the concept of iPSS based on machine tool (mt-iPSS). Depending on the concept clarification, an architecture is proposed for describing the operation of an mt-iPSS at user factory from the perspective of information and process flow. The architecture includes five key issues, i.e. accepting machining manufacturing tasks from manufacturing execution system (MES), configuring product and service based on the tasks, generating machining capacity, sustaining machining capacity, and communication between mt-iPSS and MES. Additionally, the key issues and their relations are discussed in detail. Finally, an example is run for demonstrating the proposed architecture and the five key issues.
