【 摘 要 】

Carbon fiber-reinforced polymer (CFRP) has been used in many aspects. During machining of CFRP damages are always brought in. Due to the brittleness property, the damages are closely related to the deformation in cutting area. In this study, a three-dimensional finite element model was established to study the deformation transformation in cutting area and the interactions of the deformation between two adjacent plies. An experiment was also conducted to measure cutting area deformation and sub-surface damage. The simulation results and experimental data were combined to analyze the correlation between cutting area deformation and sub-surface damage. The sub-surface damage was found have a positive relation with cutting area deformation. Based on the analyzing, a stacking strategy was proposed to reduce the damages in sub-surface. Then the optimization was verified in both numerical and experimental way.
