Holistic Approach for Condition Monitoring in Industrial Product-Service Systems

Abstract

The content of the book chapter is the development and application of a method for the cost optimized integration of a condition monitoring system for machine tools. An environment for the simulation of lifecycle costs considering the maintenance processes as well as the hardware will be described to identify an appropriate sensor concept. The approach of event based simulation allows an assessment of possible sensor concepts depending on the machine tool's performance. To realize a cost-effective condition monitoring solution using simple consumer electronics, such as Micro-Electro-Mechanical-Systems, and to provide high scalability a wireless sensor network has been developed and evaluated. It can be easily adapted to different specific applications because of decentralized data preprocessing on the sensor nodes, as well as services in the cloud. Within this network the sensors interact through a software agent system which is implemented in the machine tool and all of its subsystems. The Java Agent Development Framework will be used as a middleware. The modularization leads to a highly flexible system. Additionally, the agent system enables the interaction between the machine tool, the IPS2 provider, and its service technicians. The book chapter includes the evaluation of the method in the field of grinding machine tools by means of a feed axis.
