摘　　要：以碳纤维增强复合材料(CFRP)材料为研究对象,开展水导激光加工参数优化分析。通过正交试验优化技术获得最佳工艺条件,分析表面质量。通过正交试验获得最优参数:水射流速度160 m/s、进给速度5 mm/s、激光功率30 W、脉冲频率40 kHz。采用水导激光划槽方法形成了比干式激光划槽更干净的槽两侧,最大宽度达到395μm,最低宽度为215μm,没有形成明显的热影响区或发生熔融物附着现象。利用水导激光切割CFRP截面,水射流同时形成冲刷与降温效果,保留了完整的树脂基体,切缝处形成了光滑表面,没有产生熔渣等。Carbon fibre reinforced composite(CFRP)material is taken as the research object to carry out the optimization analysis of water-guided laser machining parameters.The optimal process conditions are obtained by orthogonal test optimisation technique,and the surface quality is analysed.The optimum parameters were obtained through orthogonal tests:water jet speed 160 m/s,feed rate 5 mm/s,laser power 30 W,pulse frequency 40 kHz.The water-guided laser grooving method was used to form cleaner groove sides than the dry laser grooving,with the maximum width reaching 395μm,and the minimum width 215μm,with no obvious heat-affected zone formation or occurrence of melt adhesion phenomenon.By using water-guided laser cutting of CFRP sections,the water jet creates both a scouring and cooling effect,preserving the intact resin matrix,and creating a smooth surface at the kerf with no slag generation,etc.
