In the new situation

composites are widely used in the manufacture of high-performance aircraft tructures

with the continuous improvement of the service range and service time of China’s new generation fighter aircraft

it is increasingly urgent to improve the reliability and service life of the body composite components. With the background of the unique application of automatic drilling and riveting technology in the field of military aviation maintenance

this paper studied the drilling characteristics of the layered damaged component

built and developed the drilling force curve prediction model and the damage interface recognition algorithm

realized the variable parameter drilling of the damaged component

and detailed characterization of the static/dynamic performance of the layered specimen before and after the damage repair. The reinforcement principle and damage repair tolerance of the drilling and riveting repair process are expounded. At the same time

the drilling and riveting process and high-precision robot in-situ drilling and riveting repair equipment for complex layered damage conditions of composite panels are developed

and a complete technical system and intelligent equipment for lamination damage drilling and riveting repair of composite panels are formed.
