摘要/Abstract

摘要：

根据机床系统的能量守恒原理，提出了一种数控车床加工过程能耗精确评估方法。参照机床系统的能量流分布，分离各能量分支的功耗,对各分支分别独立建模，最终建立数控车床系统能耗与主轴转速、进给量和材料去除率之间的函数关系。由于各分支系统建模的独立性，使得能耗模型不仅适用于数控车床系统稳定切削阶段，也适用于稳定的待机、空转和空切阶段。实验结果显示,车削过程能耗评估精度超过98%。在该方法的基础上，进一步提出改进型的机床系统单位体积能耗模型。

Abstract:

Based on the principle of conservation of energy,an accurate assessment model of energy consumption for NC turning operation was presented. According to the energy flow of machine tool system, the power of each energy branch was separated. After modeling every branch, a function was built among energy consumption and spindle speed, feed rate and material removal rate.Because of the independence of these branches, the energy consumption model suited to the stable cutting stage,and to the stable standby and idle and cutting-free stages.The accuracy of this method is confirmed over 98% by a series of turning experiments.On the strength of this method, an improved model of specific energy consumption was developed.

Key words: model , of , energy consumption;conservation of energy;machine tool system;turning process;specific , energy , consumption
