In order to achieve high-quality and high-efficiency cutting of carbon fiber reinforced composites,water-jet guided laser processing is used for the CFRP microgroove processing.The influence of the laser power,scanning speed and scanning path overlap rate on the width of the heat-affected zone and the material removal rate are investigated by the orthogonal and one-factor experimental methods and optimized with this goal in mind.The results show that the la-ser power and the overlap rate of the scanning path have a significant effect on the width of the heat-affected zone and the material removal rate.When the laser power is 35 W,the scanning speed is 4 mm/s and the scanning path overlap rate is 40％,the width of the heat-affected zone is 184.484 μm,and the material removal rate is 0.068 mm3/s,which can obtain smaller width of the heat-affected zone and higher processing efficiency.
