Base on the process requirements of typical composite components in the field of aerospace and national defense and aimed at Kevlar fiber reinforced composite structure characteristics of anisotropy, low interlaminar strength, heat-sensitive, force-sensitive etc, and the challenges of severe damage such as avulsion , delamination and burns during the process of make hole or edge trimming, starting from the cutting mechanism of the material, the removal mechanical behavior can be revealed. The model of temperature field and thermal stress field in the process of machining hole will be established, furthermore, the time-varying law of the force and heat in the processing will be analyzed, the formation mechanism of cutting damage under the effects of force, heat and the coupling can be clarified. On the basis of basic experiments and theoretical analysis, researches on developing diamond abrasive tools and exploring the new principle of grinding-trimming process will be conducted to explore the low damage hole-making strategy for composite components by reducing the cutting force and heat. The project has great significance for the promotion and the development of large-scale composite material component processing technology.
