ConspectusIn the past several decades, electrochemical machining (ECM) has enjoyed the reputation of a powerful technique in the manufacturing industry. Conventional ECM methods can be classified as electrolytic machining and electroforming: the former is based on anodic dissolution and the latter is based on cathodic deposition of metallic materials.

Helical groove of micro drill is capable to carry away reaction products out of the machining zone and hence to improve machine accuracy and depth in electrochemical machining process. This work presents an investigation of electrochemical machining of micro deep holes by using micro .
In the former research, the ultrasonic vibration technique had been adopted in the electrochemical micro drilling to exclude the reaction products in the interelectrode gap, while the ultrasonic cavitation phenomenon generates micro jet with strong impulse force, which impacts the insulation coating and speeds up the damage of the insulation coating.
Micro electrochemical machining is becoming increasingly important in the microfabrication of metal parts. In this paper, the machining characteristics of micro electrochemical milling with nanosecond pulse were studied. Firstly, a mathematical model for the localization control of micro electrochemical milling with nanosecond pulse was established.
1. Introduction. Micro electrochemical machining (μECM) is a nonconventional machining process based on electrolysis. It has become an attractive research area due to the fact that this process does not create any defective layer after machining and obtains better surface.
µm to 1mm is termed as micromachining. Electrochemical micromachining (EMM) is proved itself as a promising micromachining process that has various advantages like no wear on tool, no cutting force, stressfree machining surface, with ability to machine the complex structures precisely.
For 3D micro machining of hard metals, a few technologies such as micro mechanical milling, micro electrodischarge machining (EDM) and electrochemical machining (ECM) are available. Micro milling can be used to machine micro structures at high speed and low cost [2, 3].
