| Summary: | Micro-EDM has become one of the most accepted advanced
manufacturing technologies in micro-level fabrication. One of the main
challenges in micro-EDM is to fabricate non-circular electrode. In order to
overcome this challenge, this study presents a simple and inexpensive
process to fabricate non-circular electrode by using localised electrochemical
deposition (LECD). In this process, electrode was fabricated with the help of a
non-conductive mask, which was placed between the anode and the cathode
where the cathode was placed above the anode, and mask and the system was
immersed in a plating solution of acidified copper sulphate. The micro-EDM
was carried out by the deposited electrode without changing or removing its
orientation. In order to fabricate high aspect ratio deposited electrode both
open loop and close loop feedback system has applied. For comparing the
two-control system, both the process was monitored during the time of
deposition by measuring current density. It is found that, by using proper
operating conditions and close loop control system high aspect ratio
microstructure can be fabricated. |
