Wire-cut Electric Discharge Machining is used to cut conductive metals of any hardness or that are difficult or impossible to cut with traditional methods. The objective of the present work is to investigate the effects of the various WEDM process parameters on the machining quality and to obtain the optimal sets of process parameters so that the quality of machined parts can be optimized. The working ranges and levels of the WEDM process parameters are found using one factor at a time approach. The Taguchi technique has been used to investigate the effects of the WEDM process parameters and subsequently to predict set of optimal parameters for optimum quality characteristics in high chromium tool steels. This research outlines the Taguchi’s parameter design approach, which has been applied to optimize machining parameters during machining process. This procedure eliminates the need for repeated experiments and saves time. The machining parameters investigated are Peak current, T-on, T-off and Wire feed rate. A series of experiments are conducted using WEDM. An orthogonal array (L9) has been used to conduct the experiments. The raw data and S/N analysis are employed to find the influence of selected parameters on MRR. Objective of the present work is to reveal the influence of four different process parameters Peak current, Pulse on time (T-ON), Pulse off time (TOFF) and Wire feed rate on Material Removal Rate (MRR) of SS 304 material for cutting on WEDM.
