英文摘要: Abstract(#br)The small inner-walled ring grooves of the injector nozzles of hard-to-cut metallic materials are difficult to machine in aerospace and aviation field. Nowadays, electrical discharge machining (EDM) technology is often employed to machine this kind of structures. However, a time-consuming process of removing the metamorphic layer is needed after EDM process for some important workpieces. To solve this problem, electrochemical machining (ECM) technology for the inner-walled ring grooves of 1J116 corrosion-resistant material is studied. First, four basic tool cathode structures are designed with equal-clearance method and flow field simulations are performed with k-ε turbulence model to optimize their structures to ensure flow field uniformity and machining stability....
