ABSTRACT Manufacturing industry accounts for a significant part of world’s energy consumption and environmental pollutions. Machining process is a major process of manufacturing industries, plays an important role in energy saving and emission reduction. This paper established an energy-consumption model for machining processes considering the full states of machining processes. Firstly, machining processes are decomposed into activities and activity transitions according to the different characteristics of energy demand. Secondly, based on the decomposition of activities and activity transitions, the energy-consumption models of activities and activity transitions are established, respectively. Thirdly, combining with the established energy-consumption models of activities and activity transitions, this paper proposes an energy-consumption model for the entire machining processes that systematically reflects different machining states. Finally, the simulation results show that the proposed model can accurately calculate the energy consumption of machining processes and provide guidance for machine tool energy saving.

一种用于在加工系统中建立综合能耗过程的能耗模型

摘要 制造业占世界能源消耗和环境污染的重要组成部分。机加工过程是制造业的一个主要过程，在节能减排方面具有重要作用。本文建立了考虑加工过程全状态的加工过程能耗模型。首先，根据能源需求的不同特征，将加工过程分解为活动和活动转变。其次，在分解活动和活动转换的基础上，分别建立了活动和活动转换的能耗模型。第三，结合已建立的活动和活动转换的能源消耗模型，本文提出了一种系统地反映不同加工状态的整个加工过程的能耗模型。最后，仿真结果表明，该模型能够准确计算加工过程的能耗，为机床节能提供指导。
