Rhymes with the large amount of energy loss during the operation cycle of machine tools, environmental contamination occurs simultaneously. To cut down the energy cost, there is a growing need to research into the basic rules of energy consumption of machine tools. This paper focuses on the energy consumption laws of machine tools during idling period. energy consumption of machine tools over a period of time was monitored, through which a hypothesis was proposed that the idling power is related to the spindle speed. This hypothesis was verified by later conducted experiments. Two kinds of relationships were clarified, and the accuracy of the fitting curves were proved. On the background advent of low carbon economy, energy conservation and emmission reduction gradually turn into leading factor for future conomic growth.(1)Worldwide governments are all formulating policies on this field. U. S. Council for Energy—Efficient Manufacturing was established to reduce energy intesity of manufacturing.(2) China's National Outline for Medium and Long Term S&T Development also aims to promote the energy consumption of manufacturing industry to international advanced level.(3) In a manufacturing system, machine tools plays foundational role. However, the energy consumpiton and equivalent let out of machine tools are also considerable. During the use phase of a milling machine, there's 60% to 90% of equivalent CO2 given off.(4) It's urgent to probe into the energy consumption of machine tools. The idling power is very important in the energy consumption of machine tools, as it exits not only in the idling time, but also in cutting time . There used to be function of the power of machine tools(5), nevertheless the intricate theoritical parameters of the mode is too difficult to obtain. Therefore, this paper focuses on the practical analysis of idling energy of machine tools. large number of experiments were carried out to find out the internal law of energy consumption of machine tools.
