Abstract:
Technical necessities of modem sophisticated industries such as, aerospace, gas turbine, nuclear, etc., have led to the development of high strength, corrosion and heat resistance but difficult to machine metals. Economic machining of such metals is not possible by conventional methods, however, they can be machined satisfactorily by unconventional methods wherein, the metal removal does not take place due to plastic deformation and the formation of conventional types of chips.
Electrochemical Machining (ECM) is one of the most cernmonly used unconvmtional type of machining methods mainly because of its ad-:sptability to several types of operations such as turning, drilling, wire cutting, boring, deburring,etc. However, it has been felt that the capabi-lities of this process have not been exploited fully due to a lack of understanding of the mechanism of metal removal and difficulties experienced in tooling design....
