In the aerospace sector, the design and manufacturing of components are constantly challenged by extreme conditions: high temperature, high pressure, high speed, and prolonged operation. Traditional machining methods are increasingly unable to meet the requirements of next-generation materials and complex geometries. With the widespread adoption of nickel-based super alloys, cobalt-based alloys, and ceramic matrix composites, the limitations of cutting tools in terms of efficiency and tool life have become more evident. At this stage, Electrical Discharge Machining (EDM), with its ability to process high-hardness materials and intricate shapes, has emerged as an indispensable process in aerospace manufacturing.
