The purpose of the study described in this paper was to develop an energy-saving strategy for machining of multi-functional machine tools by pairing various turning and milling processes with various cutting conditions. The amounts of electric energy consumed during turning, facing, end milling, and drilling were measured and analyzed. Based on the experimental results, the most efficient machining processes and methods for reducing electric energy were identified. It was found to be important to employ severe cutting conditions as much as possible and to reduce the electric energy associated with machining of multi-functional machine tools during standby periods.
