The invention relates to the technical field of machine tool energy efficiency evaluation, and discloses a unit energy consumption performance evaluation method for a customized design machine tool. The method comprises the steps: obtaining basic function data of the machine tool, and converting the machining demands of machining different workpieces into different customized working condition demands: a finish machining working condition FM, a semi-finish machining working condition SfM and a rough machining working condition RM; calculating to obtain a mean value power parameter of the machine tool under the three types of customized working conditions by measuring a power parameter of the machine tool operation working condition; and calculating the unit mean energy consumption and the unit mean energy efficiency of the customized design-oriented machine tool by calculating the unit mean energy consumption and the unit mean energy efficiency of the machine tool under the three types of customized working conditions. According to the method, the deterministic demand of machine tool customization design and the uncertainty change of the future service process of the machine tool are represented, and the obtained unit mean energy consumption and unit mean energy efficiency can be used for reflecting the energy consumption and energy efficiency of the machine tool for completing a customized working condition task in unit time; and important support can be provided for formulating the energy efficiency label of the customized machine tool.
Description
technical field [0001] The invention relates to the technical field of energy consumption performance evaluation of machine tools. Background technique [0002] my country's mechanical processing is developing towards high-efficiency, high-quality and high-energy-efficiency manufacturing. However, the machining system with machine tools as the main body has a large volume and wide area, and the total energy consumption is huge, and the energy utilization rate is low. Therefore, improving the energy efficiency of machine tools and promoting energy saving and consumption reduction in the machine tool industry is of great significance to the realization of sustainable development strategies. Guiding the customized design of energy-efficient machine tools is inseparable from an objective and comprehensive evaluation of the energy consumption performance of machine tools. [0003] The ISO 14955 series of standards issued by the International Standards Committee provides a test m...
