Micro-EDM with Translational Tool Motion: The Concept of Micro-Electro-Discharge-Slotting
Application of micro-fabrications is immense in today’s life as many products have micro-features on it as a part of aesthetics or functionality. In this chapter, novel technique called Micro-Electro-Discharge-Slotting (MEDS) has been discussed in detail. The process can be used as an alternative in case of issues difficulties in carrying out commonly used micro-EDM process variant like micro-electro-discharge milling. Micro-Electro-Discharge-Slotting, due to its specialty in its tool actuation strategy, can reduce inaccuracies that may incur in the machined feature due to deformation of the micro-tool electrode. Further, a novel micro-electrode fabrication technique, namely foil as tool electrode (FAST) EDM, has also been discussed for cutting and dressing of micro-electrodes. The technique can be used in the absence of sophisticated micro-machining facilities to fabricate micro-electrodes with relative low mechanical distortion. To understand the parameter effects, a case study has also been discussed for both the processes.
