Wire Electrical Discharge Machining (WEDM) is an very accurate non-traditional machining process for producing parts with accurate dimensions and complex shapes. The performance of WEDM is measured by evaluating the parameters like Material Removal Rate (MRR), Surface Roughness (Ra), cracks, voids, pores and recast layer. In this paper, an attempt is made to improve the machining performance by adding multi wall carbon nanotube (MWCNT) with dielectric fluid. The MRR, Ra and surface characteristics are compared with surface that is machined using dielectric fluid with and without MWCNT. The results show that addition of MWCNT improves the MRR and surface finish.
