内容記述 | A new tool electrode having a porous structure, named porous electrode is developed for electrochemical machining (ECM). This electrode is fabricated using a powder bed fusion additive manufacturing process. Electrolyte fluid can be supplied to the machining gap through its permeable porous structure. Small pores and large porosity can be obtained using a higher laser scanning speed of sintering process, which increases the flow rate of the electrolyte. ECM results show that a flat surface is obtained with the developed porous electrode, and small pores are less likely to have an influence on the machined surface. In order to improve the roughness of the machined surface, jump motion of the tool electrode is applied, or air-bubbles are mixed into the electrolyte. The surface quality can be improved with both methods. | |||||
