CFRP (Carbon fiber reinforced polymer) exhibits anisotropy and low interlaminar shear strength, which makes it prone to inducing defects, especially at the fiber cutting angle of 135°, where subsurface damage is especially severe. This article constructs a 3D microscopic finite element model for CFRP cutting and analyzes the cutting mechanism of micro-textured tools at a 135° fiber cutting angle, and proposes use micro-textured tools with varying depths for cutting. Concurrently, incorporating the "crescent-shaped depression" morphology of bamboo rats' incisors, it is able to effectively mitigate subsurface damage during CFRP cutting while maintaining the structural strength of the cutting tool. The biomimetic gradient micro-textured tools proposed in this study can effectively reduce the overall subsurface damage during CFRP processing at various angles. Compared to non-textured and equal-depth micro-textured tools, the overall maximum subsurface damage is reduced by 44.92% and 21.99% respectively, providing an effective solution to reduce subsurface damage.
