Electrochemical machining is a relatively new technique, only being introduced as a commercial technique within the last 70 years. A lot of research was conducted in the 1960s and 1970s, but research on electrical discharge machining around the same time slowed electrochemical machining research. The main influence for the development of electrochemical machining came from the aerospace industry where very hard alloys were required to be machined without leaving a defective layer in order to produce a component which would behave reliably. Electrochemical machining was primarily used for the production of gas turbine blades or to machine materials into complex shapes that would be difficult to machine using conventional machining methods. Tool wear is high and the metal removal rate is slow when machining hard materials with conventional machining methods such as milling. This increases the cost of the machining process overall and this method creates a defective layer on the machined surface. Whereas with electrochemical machining there is virtually no tool wear even when machining hard materials and it does not leave a defective layer on the machined surface. This article reviews the application of electrochemical machining with regards to micro manufacturing and the present state of the art micro electrochemical machining considering different machined materials, electrolytes and conditions used.

“…Therefore in majority cases, machining in ns-PECM is carried out in kinematics of milling with application of electrode tool with 10 Examples of ns-PECM milling application: a a prism machined in a stainless steel sheet in two stages: fast rough machining with 143 ns pulses followed by a slow fine stag with 50 ns pulse duration (tool: cylindrical W wire with 30 μm diameter, electrolyte 3M HCl/6M HF) [6]; b micro hemisphere with 60 μm diameter machined by rough and finish cut (45 μm electrode, material: 304 SS, workpiece potential 6 V, 0 ns pulse on-time, 1 μs period) [15] diameter <100 μm. There are also examples of successful application of STM tip as electrode tool [29]. However, decrease of electrode tool dimensions causes EDL capacity decrease and then main impact on t * i has parasitic capacitance C p in external circuit.…”

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.
