Aramid honeycomb core was a kind of lightweight material with excellent properties such as high axial specific strength, high axial specific stiffness, and strong axial compressive strength, which has been widely used in many advanced aircraft, satellites, and automobiles, especially as an important lightweight structural component, widely used in aircraft flaps, doors, floors, and other parts. After the material was formed, machining was an essential process to obtain high-precision contour dimensions and assembly features. However, the characteristics of soft, brittle, discontinuous and thin-walled cause poor machinability. In order to solve the extremely challenging machining problems, domestic and foreign research teams have carried out extensive and in-depth exploration to achieve high-quality and high-efficient machining of aramid honeycomb core. The analysis and overview of the machining mechanism of aramid honeycomb core has been summarized, the fixing methods, machining tools, machining equipment and machining processes of aramid honeycomb core have been systematically summarized, the application in the machining of typical structural components has been introduced, and the future development direction has been prospected
