A discrete-event simulation approach to predict power consumption in machining processes

摘要: Whereas in the past sustainable use of resources and reduction waste have mainly been looked at from an ecological point view, resource efficiency recently becomes more issue cost saving as well. In manufacturing engineering especially power consumption machine tools production facilities is focus industry, politics research. Before machining processes can be reduced it necessary to quantify amount energy needed, identify consumers determine available degrees freedom for optimization. Simulation adequate alternative measurement during operation. However, many simulation methods are not suitable this task. This paper describes approach based on discrete-event simulation, which known logistical systems. It has adapted model operations generate workpiece-specific profiles footprints. Two-axis turning a CNC centre shown exemplary. The aim provide basis further applications such comparison optimization process chains systems combination with models.
