A Review Of Parameter Optimization Of Electro Discharge Machine By Using Taguchi Method

Electrical discharge machining (EDM) is one of the non-traditional machining processes, based on thermo electric energy between the work piece and an electrode. In this process, the material removal is occurred electro thermally by a series of successive discrete discharges between electrode and the work piece. The optimization of the parameters of the EDM machining has been carried out by using the taguchi’s method for design of experiments (DOE). In this research we have used taguchi’s method for design of experiments with three input parameters and their three levels using L9 orthogonal array. We have done 9 experiments with the tool material copper and work piece material AISI 304. The dielectric used is kerosene diluted with water. The objective of the analysis is to optimize the process parameters of EDM with the help of taguchi method and using Minitab software in terms of MMR.
