N2 - In order to predict and assess the energy consumption of numerical control (NC) machine tools, as well as improve the energy efficiency, energy consumption characteristics of NC machine tools were studied. Based on energy-consuming characteristics, the energy consumption of NC machine tools was divided into four sections: no-load energy consumption of the main driving system, no-load energy consumption of the feed system, energy consumption of auxiliary systems, and energy consumption of the machining process, including tool tip cutting energy consumption and additional energy losses. Each section was modeled on the basis of energy-consuming mechanisms and experimental statistics, so as to form the general energy consumption model of the entirety. Then experiments were conducted on a vertical machining center to study energy consumption rules using the model. The results show that the model has good applicability, and can accurately predict the NC machine tool's energy consumption and its distribution. Thus the energy consumption model is able to provide support for energy assessment and energy efficiency optimization of machining systems, which will contribute to low-carbon manufacturing.
