Abstract: According to the lubrication and cooling requirements of high-speed cutting tools, combined with the high-speed machining process characteristics of large-scale aluminum alloy panel of aircraft, different quantitative lubrication methods are realized to ensure the best cutting effect, and the functional stability and reliability of the minimum lubrication system for high-speed machining are improved, based on the optimization of the minimum lubrication mechanism and control strategy of high-speed machine tools. At the same time, it has some practical significance for system maintenance.
