| Abstract: | In order to reduce energy consumption of machine tools in waiting processes, a energy-saving control decision-making method for CNC machine tools was proposed based on transfer learning. By analyzing energy-saving control conditions of machine tools, 5 energy-saving control strategies of the machine tools in waiting processes were proposed. Considering diversity and complexity of production data, an energy-saving decision-making method was established based on deep belief networks and transfer learning. Through analyzing a case of elevator part manufacturing workshops, it is found that energy saving decision errors of this method are as 3.2%, and the total energy consumption in machine tools waiting processes is reduced by 52.5%. |
