Abstract

Electro-Discharge Machining (EDM) is a non-conventional manufacturing process which used for machining complex shapes in all type of conducting materials irrespective of the hardness for applied in aerospace industries, tool and die making industries etc. Material removal rate and surface roughness are the important performance measures in the EDM process. A reactive force is generated in the EDM process, due to the low electrical permittivity, reduces the damage to the tool and the required shape can be cut on the work piece with better accuracy. Discharge current, pulse-on duration (Ton & Toff) and gap voltage were used as the various input process parameters and to investigate their effects on the material removal rate, surface roughness were analyzed. The experiments were designed using Taguchi L9 orthogonal array, and nine experiments were conducted accordingly. All the experiments were conducted randomly. The results were also analyzed using Grey Relational Analysis (GRA), and the most influential parameters over the response were identified. The experiments conducted in the tungsten carbide super alloy work pieces using Copper tool electrode (rectangular cross section) exhibited more material removal rate in the EDM process. The material removal rate increased and the surface roughness was decrease found in the EDM process. The experimental results were also analyzed using GRA, and the optimal combination of the parameters was found to achieve the better results. The results were also confirmed by conducting a confirmation experiment.
