Electrochemical micromachining(EMM)technology for fabricating micro structures is presented in this article.By applying ultra short pulses,dissolution of a workpiece can be restricted to the region very close to the electrode.First,an EMM system for meeting the requirements of the EMM process is established.Second,sets of experiments is carried out to investigate the influence of some of the predominant electrochemical process parameters such as electrical parameters,feed rate,electrode geometry features and electrolyte composition on machining quality,especially the influences of pulse on time on shape precision and working end shape of electrode on machined surface quality.Finally,after the preliminary experiments,a complex microstructure with good shape precision and surface quality is successfully obtained.
