Abstract
This chapter accentuates the inherently persistent tool wear issue and its consequences in variants of micro-electro-discharge machining (µ-EDM). The consequences can be seen in the terms of deterioration of precision of the micro-holes and productivity. Although, the tool wear is well explored in μ-EDM and its variant processes, but a very limited efforts have been made to resolve this issue other side. A pulse discrimination system based-real-time tool wear compensation strategy in μ-EDM is anticipated to be a possible technique to get rid of the tool wear issue in μ-EDM drilling. In this regard, an approach which is basically a modification in the existing approach has been discovered and implemented to achieve the desired depth of the micro-hole(s). The proposed approach has been applied to two different work-tool material combinations and input parameters. The potentiality of the approach has been proven results by comparing it with that other trusted techniques like ‘uniform wear method’ (UWM ).
