Modeling and Optimization of Wire EDM Process
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
The present work is aimed to optimize the parameters of (WEDM) process by considering the effect of input parameters viz. Time On, Time Off, Wire Speed & Wire Feed. Experiments have been conducted with these parameters inthree different levels data related to process responses viz. Metal removal rate, surface roughness (Ra) have been measured for each of the experimental run. These data have been utilized to fit a quadratic mathematical model (RSM) for each of the responses, which can be represented as a function of the process parameters. Predicted data have been utilizedfor identification of the parametric influence in the form of graphical representation for showing influence of theparameters on selected responses. Predicted data given by the models (as per Taguchi’s L27 OA) design have been used insearch of an optimal parametric combination to achieve desired yield of the process. Taguchi techniques have been used for optimization of minimizing the surface roughness. The optimal value has been verified to the predicted value.
