刀具表面微织构与微量润滑协同技术研究进展OA

This paper systematically reviewed the research progresses of MQL and micro-textured tool technology in DMMs cutting in recent years,and focused on analyzing the synergistic mechanism and the influences on DMMs cutting performance.Compared with dry cutting,the synergistic effects of micro-textured+MQL may reduce the average cutting force by 25%to 48.3%,reduce the cutting temperature by 20%to 50%,improve the surface roughness by 15%to 40%,and extend the tool life by 1.5 to 2.4 times.The existing research is yet to be strengthened in the following aspects:first,quantitative theoreti-cal model of synergistic mechanism;second,adaptability analysis for different materials;and third,experi-mental verification of long-term stability under industrialized conditions.Future research should focus on the construction of quantitative synergistic models based on thermodynamic and tribological behaviors,es-pecially the optimization of the applications in the machining of high-strength and high-temperature materi-als such as titanium-based alloys and aluminum-based alloys,and the verification of the industrial applica-tion value through the evaluation of the long-term performance under actual working conditions.
