Abstract In order to improve the quality of laser drilling, laser drilling experiments of titanium alloy by using the waterjet assisted laser scanning machining method was investigated, the effects of process parameters on the hole diameter and hole taper of titanium alloy were analyzed by response surface methodology. The results show that the impacts of hole diameter are the laser current, pulse frequency and pump voltage in descending order. While the effects of pulse frequency, laser current and pump voltage on hole taper are in descending order. When the optimal laser current is 33.6818 A, pulse frequency is 30.6818 kHz and pump voltage is 12.6818 V, the hole entrance diameter and hole taper are the minimum, the hole exit diameter is the maximum. At the same time, it is found that the hole diameter in waterjet assisted laser machining is larger than that in the air machining, but the hole taper is reduced by 33.2%.
