Electrochemical Micromachining (EMM) System Development for Experimental Investigation

Electrochemical Micromachining (EMM) is considered to be one of the most effective advanced future micro-fabrication techniques due to its several advantages. A suitable EMM setup mainly consisting of various components and subsystems, e.g., mechanical machining unit, micro-tooling system, electrical power and controlling system and controlled electrolyte flow system etc has been developed successfully to control ECM parameters to meet the micromachining requirements. Investigation indicates most effective zone of predominant process parameters such as machining voltage, electrolyte concentration and pulse on time, which give the appreciable amount of MRR with less overcut. The developed EMM setup is a unique system and will open up possibilities for further research works.
