Abstract
Electro-Chemical-Machining (ECM) has been used in highly specialized fields such as aerospace, defence and medical industries. In recent years ECM makes use of other industries, because of the advantage. That is, ECM has no tool wear, and it can machine difficult-to-cut-metals and complex geometries with high accuracy. However, ECM has some problems such as the design of the tools, electrolyte processing disposal of metal hydroxide sludge and so on. In the present study, the three-dimensional flow field in ECM process is calculated, changing bow and sweep stacking Visualizing flow field around a jet engine blade the characteristics of the flow are investigated.
