Study on Kerosene Submerged Jet Electrolytic Micromachining

This paper proposes a non-conventional jet electrolytic machining process to further improve localization of anodic dissolution by submerging both the nozzle and the workpiece in the kerosene, and verification experiments are conducted by fabricating micro-dimples. The experimental results show that, compared to the traditional unsubmerged Jet-ECM processes, the kerosene submerged Jet-ECM process shows a better localization if appropriately low voltages are chosen, and further, it exhibits both a better localization and a bigger removal rate when a suitable working gap is also satisfied. In addition, smoother surfaces can be observed, showing a smaller surface roughness, in the all micro-dimples machined under the kerosene.
