Keywords: Electrochemical micromachining, titanium, micro feature, machining voltage 1. Introduction Electrochemical machining (ECM) is an extraordinary process in which the material removal takes place by electrochemical reaction irrespective of material hardness. ECM has the characteristic of no electrode wear and stress free.
Chemical machining and Electrochemical machining are thermal free processes, but chemical machining cannot be controlled properly in the micromachining domain. ECM process is applied to the micro machining range of applications for manufacturing ultra precision shapes; it is called Electrochemical micro machining (EMM).
Aim of the presentation Give brief information about electro chemical machining process Show the ECM's working principles and tools Define the advantages and disadvantages Brief informations about application areas, economics, products and developments.
The main advantages of the electrochemical machining (ECM) process, such as high material removal rates and smooth, damagefree machined surface, are often offset by the poor dimensional control and process stability resulting from the complex and stochastic nature of the interelectrode gap (IEG) states.

Electrochemical Machining: Significant advances during the 1950s and 1960s emerged ECM as an efficient technology, in the aerospace and aircraft industries.
Mask electrochemical machining (MECM), which combines photolithography and micro electrochemical machining, is widely used to prepare micropits arrays on engineering metal materials because of its low cost, easy operation process and high machining efficiency [19 – 22]. Here, we extended this technique into the area of fabricating superhydrophobic post arrays on aluminum (Al) substrates.

Compared with mechanical machining, ECM has several advantages, such as avoiding tool wear, none thermal or mechanical stress on machining surfaces, as well as high removal rate. Moreover, ECM is capable of making complex threedimensional structures and is appropriate for flexible, fragile, or fissile materials even materials harder than the machining tool.
