초록

Electrochemical discharge machining (ECDM) is a very recent technique in the fabrication of the micro-electro-mechanical system ( MEMS ) devices. This paper presents the experimental results of the machining of micro-holes on pyrex glass substrates by use of ECDM. Electrolyte is used with a KOH aqueous solution, cathode with copper, anode with platinum, and tool feed system is applied with gravity feed system. Already established experimental results were taken under the condition of constant voltage frequency. However in this paper, the effect of variation of the voltage frequency and duty ratio is considered. In this experiment, it is measured the ECDM performances with variation of the voltage frequency and duty ratio under the conditions of constant other machining variables. ECDM performances are described by the hole depth, and the top hole diameter.
