Theoretical and experimental researches were conducted to analyze the performance of laser-induced biomimetic ceramic tools in interrupted cutting. The formation of biomimetic microscopic structure and its effects on the tool load and the mechanical behaviors were integrated in tool performance analysis. This work investigated the influences of the laser pulse angle and number on the ablation of the ceramic. A two-dimensional microstructure model was utilized when investigating the influences. The distribution variation of the heat source intensity was considered in the analysis of the influences. Fractal theory, damage mechanics and fracture mechanics were employed to analyze the mechanical behaviors for the biomimetic ceramic. These mechanical behaviors included the fractal dimension corresponding to the microcrack caused by laser, the initial integrated damage and the fracture toughness. A performance indicator was established for the biomimetic ceramic tool considering the tool load and the mechanical behaviors. It was found that the maximum depth caused by the laser pulses can be used to mirror the mechanical behaviors. The fractal dimension had a potential for the effective evaluation of the initial integrated damage and the fracture toughness. When the laser angle was 60° and the number of scans was 3, the biomimetic ceramic tool exhibited the best performance. The balance among the tool load, the initial integrated damage and the fracture toughness should be achieved to obtain the best tool performance.
