For successful commercial adaptation of the μ-EDM (micro electro-discharge machining) process, there is a need to increase the process efficiency by understanding the process mechanism. Developed in the mid 1970s In the mid 1980s, the EDM techniques were transferred to a machine tool Today,it is a viable technique that helped shape the metal working industry. Electrical discharge machining involves immersing the workpiece in machine liquid and removing material via melting-fusion, through the use of current discharges between two electrodes. Micro Electro Discharge Machining (uEDM) is a serial rapid prototyping subtractive technique for the machining of 3D complex shapes (also with high aspect ratio) in conductive materials (metals or heavily doped semiconductors) using the localized removal of the material through the generation of high frequency sparks between a tool and the workpiece. Micro electrochemical discharge machining (micro ECDM) is an emerging nontraditional fabrication method capable of micromachining ceramic materials like glass. It explores constraints in the fabrication and usage of high aspect ratio LIGA-fabricated electrode arrays, as well as the limits imposed by the pulse discharge circuits on machining rates. Micro-Electrochemical Discharge Machining (μ-ECDM) is non-contact type hybrid/combined machining process which comprises two dissimilar energies as thermal and electrochemical. (Electrical Discharge Machining) involves the removal of metal from a workpiece by sending an electric current through an electrode or wire. In a previous paper, the authors presented a reliable reverse modeling approach to perform such tasks based on a crater-by-crater simulation model and an outer optimization loop. Electrical Discharge Machining (EDM) is ideal for intricate burr-free cutting of intricate contours or cavities in hard materials, eliminating the need to soften the material before machining, and then re-harden it through heat-treating. The objective of this study is to investigate the feasibility of machining micro-holes on the non-conductive Aluminum Nitride (AlN) ceramics using micro-electro-discharge machining (EDM) process by exploiting various coating techniques. nanofiber assisted micro electro discharge machining of reaction-bonded silicon carbide Pay Jun Liewa,c, Jiwang Yanb,∗, Tsunemoto Kuriyagawaa a Department of Mechanical Systems and Design, Tohoku University, Aramaki Aoba 6-6-01, Aoba-ku, Sendai 980-8579, Japan b Department ofMechanical Engineering, Faculty Science and Technology, Keio University, Hiyoshi 3-14-1, Kohoku-ku, Yokohama … Processing Characteristics of Micro Electrical Discharge Machining for Surface Modification of TiNi Shape Memory Alloys Using a TiC Powder Dielectric.
