Energy efficiency in machining production
Energy is becoming ever more expensive. On the one hand, (conventional) energy reserves are dwindling without, up to now, a complete solution that permits adequate amounts of energy to be obtained cost-effectively from renewable forms of energy. On the other hand, production and commerce are not possible without energy. By increasing the energy efficiency of production processes, greater added value can be achieved with less energy usage.
In this paper the energy consumption of machine tools and the machining processes running on these machines are analysed. Effective, specific approaches for increasing energy efficiency are derived from this analysis with a focus on the optimisation of tools and machining processes.
Motivation
The usage of energy is essential for modern production and commerce. Global population growth, increasing quality of life and economic growth are the drivers continually increasing energy consumption. On the other hand, global energy consumption is limited by the restricted availability of energy sources such as coal, oil or even bio-fuels. Global warming and its consequences along with the pollution often linked with energy transformation also ultimately limit energy consumption. The increasing demand for energy within the current limits is resulting in increasing energy prices over the long term.
Against this background, the energy efficiency of production processes is a technology driver that will also make modern production possible in the future. But how and by making which specific changes can energy efficiency be increased in machining production?
