Outline of Final Research Achievements

Electrochemical machining (ECM) is one of the most effective methods for micro machining since the machining is carried out without a contact between the tool electrode and workpiece. Moreover, since the tool electrode wear does not occur, a thin wire electrode can be used as the tool electrode. In this study, micro wire ECM machine was newly developed, and machining characteristics of wire ECM were investigated. Micro grooves were machined using thin wires with a diameter of several micrometer to several tens of micro meter, and optimal machining conditions were derived to decrease the groove width. As a result, a micro groove with a width of 8μm could be successfully machined using a wire electrode of 5μm in diameter.
