Abstract:

During electrochemical micromachining (EMM) , materials are removed in the form of ions based on the anodic dissolution mechanism, so it should be a promising technique for micromachining . A new kind of experimental setup of EMM was developed successfully, which is in fact a multifunctional machine tool, and micro-electrode tool can also be fabricated on the same machine tool. The developed experimental setup for EMM consists of feed unit, micro electrode fabrication unit, ultra-short pulse power supply, short circuit detection of machining current and so on. The experiments on micro electrochemical milling (micro EC milling) of typical micro-structure samples by the micro electrode tool rotating like micro milling cutter were carried out. The new feed strategy of micro EC milling was adopted. The comparative process experiments were carried out to explore the machining laws to meet the requirements for micromachining. At optimized parametric combinations, the micro triangle and the micro beam with width of about 50μm were milled on the stainless plate 304 by micro EC milling.
