[Abstract]:In order to understand the level of energy consumption in mechanical manufacturing industry, a feasible and applied energy efficiency evaluation method is put forward, which is based on the previous research results, such as energy efficiency model and evaluation index system of machining workshop. A set of general energy efficiency evaluation method framework and its key technology for machining system are presented. The method includes six steps: boundary division of energy efficiency evaluation, determination of energy efficiency evaluation index, energy efficiency data collection, selection of energy efficiency evaluation tools, output of energy efficiency evaluation results and analysis of energy efficiency level. Based on practicability, a set of energy efficiency evaluation index of machining system for process (equipment) layer and workshop system layer is proposed, which reflects the energy efficiency of workpiece processing process and the energy efficiency of product unit output in macro level. This paper presents a method of energy efficiency data acquisition based on the combination of structured and object oriented data availability. The effectiveness of the energy efficiency evaluation method is verified by a case study. The energy efficiency evaluation flow and key technology of machining system are described in detail, and the maneuverability of energy efficiency evaluation is enhanced.
