Performance Investigation of Wire EDM Process Parameters

Abstract

It is exceptionally difficult to create confusing geometry in such a material using traditional machining measurement. At present, companies use a non-regular machining strategy which uses energies like electricity, chemical, sound, light, etc. which are useful for machining hard materials. WEDM machines are used to cut complex and simple patterns and have the potential to achieve the maximum production capacity since the last few decades. This study was carried out in two parts. The first segment was consolidated with analyses of the Taguchi method depending on the signal-to-noise ratio (S / N) and regression modelling for the S / N ratio. In the second segment, the model condition was created using the RSM methodology. L16 orthogonal array was used with four levels of parameters namely, pulse on time, pulse off time, wire feed rate and peak current to find the effects on optimal response variables namely, cutting time, cutting rate, overcut and dimensional deviations. The results of the regression analysis showed that there was significant effect of pulse on/off and peak current on the cutting time and for cutting rate there was also significant effect of wire feed rated. Therefore, it can be concluded that all the four process parameters can affect the response variables.
