A model- and signal-based power consumption monitoring concept for energetic optimization of machine tools

As energy consumption is one of the main drivers for production and operational cost of a product, it is necessary to make operators of manufacturing units and machine tools aware of the current power consumption of their operating equipment. However, it is not sufficient to provide the current overall power consumption but to give different levels of detail. This paper presents an approach to combine power measurements, control signals and information with consumption simulation models to provide the operators with highly detailed power consumption data and how it is distributed over the components of their machine tools. An implementation of the monitoring approach on a HSC milling machine is presented in detail, followed by an overview of its use for energetic optimization
