5.2.14 Advancement in ECM

ECM is one of the most promising modern machining methods due to its versatility in applications. It has wide range of applications in modern manufacturing industries starting from shaping and finishing of large parts to fabrication of micro components. However, several issues, e.g., stray machining, tool design, electrolyte flow path design as well as control and monitor of machining gap, etc. need to be improved for making it more acceptable for commercial purpose in coming years. Although, researchers have attempted to solve some of the key issues through the advancement of the ECM process which are discussed hereunder:

  1. (i) Control of end gap

The major problem in ECM is the online control of gap between tool and ...
