Considering the environmental impacts of manufacturing systems has become a major topic in the last years. For the case of machine tools, the environmental impact is basically determined by the consumption of electrical energy. The underlying power demand results from an interaction of different components and is not static but rather highly dynamic depending on the operation mode. Hence, as a prerequisite for pursuing the efficient usage of energy in machine tools, it is crucial to understand the power demand and resulting energy consumption. Metering the power demands of machine tools is therefore an essential prerequisite to identify, analyze and evaluate main drivers of electrical energy consumption and derive improvement measures. Against this background, this paper presents practical procedures and tools to meter the power demand and conclude the energy consumption of machine tools as an initial step to improve energy efficiency.
