Research on unconventional methods of cylindrical micro-tools manufacturing

In case of electrochemical and electrodischarge milling the minimal feature size depends on proper selection of machining parameters and electrode-tool size. Usually, as the electrode-tool the commercially available cylindrical rods are applied, so one of the main technical issues is to provide precise rotation and high tool stiffness. In the paper result of cylindrical tools in-situ manufacturing for EC and ED-micro milling process will be discussed. The special attention will be paid to electrochemical etching and electrodischarge turning application in the unconventional-milling process chain.
