Abstract

Section titled ā€œAbstractā€

Carbon fiber reinforced polymer (CFRP) circular honeycombs are advanced materials for aerospace applications, while their thin-walled structure poses machining challenges. This study systematically investigates surface quality and damage in grinding CFRP circular cells with a diamond saw blade. The geometric kinematics were analyzed, and the grinding experiments with a diamond saw blade were conducted. The effects of grinding parameters (speed, feed rate) and methods (up/down grinding) on cutting paths, central angle, cutting exit angles, and cutting forces were evaluated. The machining quality of the kerf end face and side face was examined, including surface roughness measurements and quantitative evaluation of end face burrs and side face burrs. The effects of grinding speed, feed rate, and grinding methods (up/down grinding) on surface quality and machining damage were analyzed. By observing the microscopic morphology of the machined surfaces and analyzing the material removal process, the machining damage mechanisms were investigated. Results show that down grinding reduces cutting force Fy by more than 61.2 % compared to up grinding, with end face burrs decreasing to 25 % in quantity and 50 % in length. Increasing the grinding speed and reducing the feed rate can reduce cutting force, minimize burr damage, and improve surface quality. This study elucidates the mechanism of surface quality formation and damage generation during the grinding of thin-walled carbon fiber composites, providing guidance for process development.
