摘　　要：为方便快捷地预测和优化机床服役过程各阶段能效,建立了基于铣削加工特征的机床服役过程能效计算模型,机床服役过程主要包括启动、空载和加工3个阶段,这一过程能效主要由辅助能效和加工能效构成。将实验数据进行分析,获取相应的修正系数后,通过建立的数学模型计算得出机床各阶段能耗,将各阶段能耗与总输入能耗之比作为各阶段的能效。最后对一台数控铣削加工中心进行试验研究,结果验证了该计算方法的准确性。该方法可应用于机床能效的评估与预测。n order for quick and easy prediction and optimization of energy efficiency in different stages of the service process of machine tool, a machine tool service process calculation model of energy efficiency was established based on milling characteristics, which mainly included Start-up, no-load and processing of three stages. This process was mainly composed of auxiliary and processing efficiency. By accessed to the corresponding correction coefficient through the analysis of experimental data, the machine tool energy consumption of each stage was calculated by the established mathematical model. The energy efficiency at each stage was the ratios of that energy consumption to the total input energy consumption. Finally, the experiments of study are conducted on a CNC milling ma- chining center, and the results demonstrate the accuracy of the calculation method, so the calculation model can be applied to machine tool efficiency evaluation and prediction.
