Abstract

This study investigates drilling-induced damage in hybrid composites, specifically examining the interplay between cutting parameters and hole delamination. Three drill types—high-speed steel (HSS), 5% cobalt-coated high-speed steel (HSS-Co5), and solid carbide—are analyzed for their distinct impacts. The research underscores the substantial influence of feed rate and rotational speed on delamination, noting that increased feed rates exacerbate the issue. Notably, HSS drills exhibit superior performance in mitigating delamination compared to other types. The study unequivocally demonstrates that operating the HSS drill at lower feed rates and rotational speeds significantly minimizes delamination, achieving remarkable results at a feed rate of 0.04 m/rev and 1592.35 rpm. While rotational speed’s consistent significance is limited, with the rotation speed 2388.53 rpm, the delamination factor of the HSS drill recorded the smallest values with all the cutting conditions of the tests carried out. These insights emphasize the critical need for optimized cutting parameters when drilling hybrid composites, providing valuable guidance for engineering applications and materials science.
