Machine tool selection method facing highest energy efficiency during whole usage stage of machine tool

Abstract

The present invention discloses a machine tool selection method facing the highest energy efficiency during the whole usage stage of a machine tool. The method comprises the following steps of establishing an expected processing workpiece set WT; establishing a candidate machine tool set MT; establishing an inherent energy efficiency characteristic matrix for each candidate machine tool in the candidate machine tool set MT; according to the inherent energy efficiency characteristic matrix of each candidate machine tool, establishing an inherent energy efficiency characteristic correlation matrix E containing all candidate machine tools; establishing a processing characteristic matrix for each candidate machine tool in the candidate machine tool set MT; for each candidate machine tool, calculating an equivalent parameter; according to the processing characteristic matrix and the equivalent parameter, constructing an equivalent processing characteristic matrix for each candidate machine tool; according to the equivalent processing characteristic matrix of each candidate machine tool, separately establishing an equivalent processing characteristic correlation matrix for each candidate machine tool to process the all workpieces in the expected processing workpiece set WT; according to the inherent energy efficiency characteristic matrixes and the equivalent processing characteristic correlation matrixes, calculating the energy efficiency of the candidate machine tool MT<m>, and selecting the candidate machine tool having the highest energy efficiency as the purchase machine tool.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a method for pre-evaluating the energy efficiency of a machine tool during the entire use period. Background technique [0002] In recent years, improving the energy efficiency of manufacturing systems has become an important strategy for the sustainable development of manufacturing industries in various countries. At the same time, under the pressure of increasing energy prices and environmental policies, manufacturers urgently need to improve the energy efficiency of manufacturing systems. Considering that the machine tool is the main energy consumption of the manufacturing system and has great potential for energy saving, it is very necessary for the manufacturer to purchase suitable machine tools in the stage of building the manufacturing system, so that the energy efficiency of the machine tools in the entire future use stage is as high as possible.
