Addressing the challenges of machining honeycomb structures made of superalloy for aero engines,the feasibility of blasting erosion arc machining(BEAM)of honeycombs was proposed and validated.Furthermore,the advantages of BEAM in enhancing machining efficiency and precision were analyzed.The experiments employed an internal flushing disc electrode,investigating the effects of flushing pressure and principal discharge parameters on the quality of honeycomb machining.The results indicated that flushing pressure plays a significant role in improving machining quality,particularly when exceeding 0.6 MPa,which notably enhances the surface quality of the machining while reducing electrode wear.This research effectively validates the potential of BEAM for aerospace honeycomb structures and provides a theoretical and experimental basis for the optimization and development of related technologies.
