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
