Abstract

An evaluation system for edge collapse of graphite/ceramic composite material during drilling is proposed in this study. The system consists of four indicators: layered delamination factor, area damage factor, average deviation, and maximum radial distance, which are used to comprehensively evaluate edge collapse defects. The effects of drilling parameters on each indicator and drilling force were investigated, and the laws governing the influence of drilling parameters on drilling force and edge collapse of graphite/ceramic composite materials were obtained. This research provides a theoretical basis for optimizing drilling parameters and reducing edge collapse defects. The application of this evaluation system contributes to improving the drilling quality and efficiency of graphite/ceramic composite materials, making it valuable in practical applications.
