Abstract

Abstract: In order to obtain higher service performance, high performance materials and complex structures are widely used in aerospace field, which pose great challenges to manufacturing technology. As the most mature and widely used non-traditional machining method, Electrical Discharge Machining (EDM) is widely used in aerospace products, especially in engine products, because it has the characteristics of non-contact, no cutting force; also because the processing performance is not affected by mechanical properties such as material strength, toughness, hardness and stiffness. This paper focuses on the research progress and successful application cases of EDM in aerospace manufacturing field at home and abroad. In addition, with the development of intelligent manufacturing technology and rapid penetration into the field of aerospace manufacturing, domestic EDM intelligent manufacturing technology solutions are constantly emerging. Several typical solutions of EDM intelligent manufacturing system are also introduced in this paper.

Key words: EDM technology, EDM die-sinking, wire EDM, high speed EDM of small holes, arc discharge machining
