Abstract—The developments in EDM have opened up new avenues for finishing of hard and brittle materials with nano surface finish, high tolerance and accuracy. A single wall Carbon nano tube (SWCNT) is having high Mechanical and Electrical Properties specifically High Electrical Conductivity. By using these properties of the single-wall carbon nano tube mixed with dielectric fluids in EDM process to analysis the surface characteristics like surface roughness, micro cracks in AISI D2 tool steel a work piece material which is very much used in moulds and dies. Experimental results indicate that the surface texture after EDM is determined by the discharge energy during processing. An excellent machined nano finish can be obtained by setting the machine parameters at low pulse energy. The surface roughness and the depth of the micro-cracks were proportional to the power input. Furthermore, the SEM application yielded information about the depth of the micro-cracks is particularly important in the post treatment of AISI D2 tool steel machined by EDM.
