Abstract

   Greening technology in the manufacturing has been developed extensively. Currently, with the IoT technology development and the improvement of computing power, the development of methods for improving energy efficiency of the entire manufacturing system, not individual devices, has become active. In such a situation, we aim to high efficiency of the energy consumption in the system by optimizing the cutting conditions of machine tools from the viewpoint of the entire system. In this study, a manufacturing system consisting of multiple machine tools was used as a test bed, and it was verified whether the peak demand value could be reduced by changing the machining speed of one machine tool. The appropriate processing speed was determined based on the power consumption model constructed by simple preliminary experiments. As a result of numerical simulation based on the measured values, the peak demand value in the entire manufacturing system was reduced by an appropriate machining speed. By determining the processing conditions using the power consumption model, efficiency of the energy consumption in the entire manufacturing system was improved.
