EMO HANNOVER 2017

Benefits of Predictive Maintenance In classical antiquity, the visions of the future revealed by the Oracle of Delphi were often enigmatic and even incomprehensible. By contrast, the production scientists of the Fraunhofer Institute for Production Systems and Design Technology (IPK) are able to foresee the future of machine tools a lot more clearly and accurately with the aid of predictive maintenance. Eckhard Hohwieler and Claudio Geisert, both from IPK in Berlin, report on the salient considerations and the role the EMO Hannover 2017 exhibition plays in their work.

Artificial intelligence in the data cloud

The acceptance and the success of predictive maintenance stands and falls on the quality of the information obtained and the benefits to the customer of the predictions concerned. A priority is the development of high-performance evaluation logics, so as to effectively filter out the necessary information from the mass data and to use it to calculate dependable predictions for machines and customers. The requirements involved, however such as cost reduction, transparency in the production and maintenance processes, plus better resource planning, have basically remained the same.
