Abstract: Integral blade is an important development direction of aeroengine technology. However, the current integral blade is made of difficult-to-machine materials. How to achieve high quality and high efficiency machining of integral blade is one of the most urgent problems in the field of mechanical manufacturing. Roughening of integral blade blanking by Abrasive Water Jet (AWJ) technology is an effective means to improve the processing efficiency of integral blade and reduce the cost of expensive milling tools. In this paper, the domestic and foreign studies of the material removal mechanism of AWJ machining, the trajectory optimization of complex surface, the combination optimization of multi-physical and mechanical parameters, and the intergral blade blanking equipment are summarized. On this basis, the solutions to some key problems of the intergral blade blanking with complex surface structure are put forward. The development trend of AWJ in high efficiency machining of complex curved surface parts is pointed out. The application and feasibility of AWJ in high efficiency machining of complex curved surface parts are prospected.

Key words: hard-to-machine material, complex curved surface, integral blade, abrasive water jet, blanking
