Electrochemical micromachining (ECMM) is a promising micromachining technology, since it offers several advantages which include absence of machining forces and residual stresses, no tool wear, good surface finish, adaptability to various processes, and ability to machine complex 3D micro features with the material removal/addition unit at the atomic scale (0.1nm or even smaller).
To realize ECMM, the foremost thing is to prevent the stray erosion caused by the distributing electric field in the convent...
