OPTIMIZATION OF CUTTING SPEED PARAMETER FOR ROUNDNESS STUDY IN WIRE EDM FOR DIFFERENT MATERIALS BY TAGUCHI METHOD

In the present paper review is directed of test investigations did to consider the impact of EDM parameters on cutting speed (CS), electrode (EWR), surface roughness (Ra) and dia material over cut in erosion safe tempered steels. The non-contact machining method has been constantly advancing from a negligible device and bite the dust making procedure to a small scale application machining elective pulling in a lot of research interests and Electro chemical machining (ECM) offers a few extraordinary favorable circumstances including higher machining rate, better accuracy and control, and a more extensive scope of materials that can be machined The objective of this paper is to present the results of a study on the effect of the wire electric discharge machining of stainless steel SS-316, H13 and EN24 for machining in W- EDM. The present research focuses on the roundness parameters for different materials and at different thickness.
