TITLE: OPTIMIZATION OF E.D.M PROCESS PARAMETERS USING TAGUCHI ALGO. AND MINITAB STATISTICAL SOFTWARE- A REVIEW AND CASE STUDY

ABSTRACT: In EDM various techniques can be applied to improve the material removal rate (MRR), surface roughness (SR) with different electrode combinations. However, the machining parameters are also effective while machining. In this study, an experiment is performed to analyze the effect of machining parameters viz. discharge current (Ip), pulse on time (Ton), voltage (v) over the responses of MRR and SR. For this Tungsten carbide tool or electrodes used while the work piece chosen as AISI 304 stainless steel. For the conduction of experiments, L9 orthogonal array is used to complete the runs. For analysis and explanations Minitab statistical software with Taguchi Equations is employed. Since optimum material removal rate is desired so higher the better criteria of Taguchi signal to noise ratio is employed for material removal rate. For surface roughness, lower the better criterion is advised. Through this study, not only the optimal settings for the MRR and SR is obtained but also the main parameters that affect the performance in EDM processes can also be found. The predicted optimal settings ensured maximum material removal rate and minimum surface roughness
