| Abstract: | Electrical Discharge Machining is a machining method primarily used for hard metals or those that are impossible to be machined with traditional techniques. The experimental investigation of material removal rate and surface roughness and hardness of oil hardened non-shrinking steel and high carbon high chromium with brass electrodes using EDM machine was carried out in this paper. This investigation presents the analysis and evaluation of heat affected zones and surface finish of the work piece using different tool electrodes and varying the machine parameters. The commercial grade kerosene oil has been used as dielectric fluid. The effect of various important EDM parameters such as discharge current (Ip) 2 to12A, pulse duration (Ton and Toff) and sparking voltage (V) of 80±5% have been used to yield the response in terms of Material Removal Rate (MRR) and hardness, surface roughness. Further a detailed analysis of the heat affected regions was also been carried out by sing scanning electron microscopy. Apart from the important role that Micromachining and ultra-precision machining has provided to the development of improved or innovative miniaturized products, these techniques have also attracted the interest of the researchers to obtain the highest accuracy and a thorough analysis of the principles governing the material removing mechanisms. |
