“…Another method is applying ultra short voltage. It was successfully demonstrated for threedimensional machining of copper and silicon with submicrometer resolution (Kozak et al, 2009;Kock et al, 2003). Here we apply this method to the machining of stainless steel.…”

Problem statement: Electrochemical Machining (ECM) is a prospective technique in micro machining. The productions of work piece in ECM are precipitation of hydroxide, which will block the machining gap. To prevent the formation of hydroxide, acids were often used. To machining work piece which is not acid-resistant, acids are not suitable. Approach: This study is conducted to find the effects of complexing agent on Electrochemical Micro Machining (ECM) of stainless steel. Compared to acids, the complexing agent is non-toxic and non-corrosive. ECM of stainless steel by applying short pulses in sodium chlorate electrolyte added with complexing agent is researched. Ethylenediaminetetraacetic acid disodium salt (EDTA-Na2) is a kind of widely used complexing agent. The usage of EDTA-Na2 prevented the formation of hydroxide. On the other hand, without EDTA-Na2, the electrode was attached with precipitation of hydroxide and short circuit occurred frequently. Results: Experiments results indicated that EDTA-Na2 can avoid the short circuit and not increase the side gap of electrochemical machining. Conclusion: EDTA-Na2 can form complex compound with ions of anode and dissolved in electrolyte. It is a kind of effective complexing agent in electrochemical machining of stainless steel.

One of the most effective way of electrochemical machining (ECM) accuracy increase is to carry out process with application of voltage pulses. In one of the variants of ECM, ultra short (nono-or picosecond range) voltage pulses are applied. It gives possibility to achieve high localization of electrochemical dissolution process and allows to machine microparts with accuracy less than 0.01 mm. However, because of the process principles, this variant of ECM has number of limitations which stop its wider application in micromanufacturing industry. Based on the literature review, the physical principles of ultrashort voltage pulses electrochemical machining were presented and anodic dissolution localization issues were discussed. Also, differences between other electrochemical machining variants were underlined. It gave possibility to identify limitations and future perspectives of industrial applications.

“…A further adaptation is the introduction of a pulsed current power supply. First exploited in general electrochemical machining [37,44,45] inhomogeneity in the flow field is reduced due to the rapid updating of the electrolyte. This ensures that machining is restricted to beneath the jet as the electric double layer takes longer to form in the lower current density areas at the periphery of the jet [46,47].…”

a b s t r a c tElectrochemical jet processing techniques provide an efficient method for large area surface structuring and micro-milling, where the metallurgy of the near-surface is assured and not adversely affected by thermal loading. Here, doped electrolytes are specifically developed for jet techniques to exploit the Gaussian energy distribution as found in energy beam processes. This allows up to 26% reduction in dissolution kerf and enhancements of the defined precision metric of up to 284% when compared to standard electrolytes. This is achieved through the filtering of low energy at discrete points within the energy distribution curve. Two fundamental mechanisms of current filtering and refresh rate are proposed and investigated in order to underpin the performance enhancements found using this methodology. This study aims to demonstrate that a step change in process fidelity and flexibility can be achieved through optimisation of the electrochemistry specific to jet processes.
