metal-cutting machine; energy efficiency; balance; integral characteristic

Methods of determining the energy efficiency of machine tools are analyzed, including methods based on the input energy balance, the expenditures in machining, and energy losses in the shaping structure of the machine tool. The energy efficiency may be assessed in terms of the energy ratio of the physical pro\'02 cesses within the machine tool. On that basis, metal\'02cutting machines may be classified by energy efficiency.
