摘要(Abstract)：
为降低碳纤维增强树脂/钛合金(CFRP/Ti)复合材料在加工过程中受到的损伤程度，采用阶梯微齿刀具和轴向振动辅助处理对CFRP/Ti复合材料进行了振动测试，分析了加工性能随振幅的变化。研究结果表明：受振动作用时刀具的轴向进给发生改变，形成了循环的轴向力，当钻尖进入材料内部后，轴向力将会受到振动显著影响；辅助振动时，没有形成长切屑，入口表面也未受到刮擦影响；当振幅提高后，形成了更大的撕裂因子，造成制孔质量的波动性；合适的振动条件下CFRP孔壁表面形成了更少凹坑，深度发生了增大。
In order to reduce the damage degree of carbon fiber reinforced composites/titanium alloy(CFRP/Ti) composites during machining, the vibration test of the CFRP/Ti composites is carried out by the step micro-tooth tool and the axial vibration assisted processing, and the variation of the machining performance with the amplitude is analyzed. The results show that the axial feed of the tool changes under vibration, and the cyclic axial force is formed. When the drill tip enters the material, the axial force will be significantly affected by the vibration. During the auxiliary vibration, no long chips are formed and the inlet surface is not affected by scratching. When the amplitude is increased, a larger tearing factor is formed, resulting in the fluctuation of the quality of the hole making. Under the right vibration conditions, fewer pits are formed on the surface of CFRP pore wall, and the depth increases.
