The extended connotation of energy efficiency of machining systems is summarized firstly. The state of the art of energy efficiency research on machining systems is investigated through the lenses of general overview and category of research objects. Based on the review, a content architecture framework of energy efficiency research on machining system is advanced, which includes three objects (machine tools, workpieces and system), five basic technology issues (the energy efficiency of energy consumption links and energy consumption components, the modeling of energy consumption and energy efficiency, the energy efficiency characteristics of machine tools and workpieces, the evaluation of energy efficiency, and the energy efficiency monitoring and management of machining syst
