Metal Removal Rate Optimization in Electric Discharge Machining Process
نویسنده
چکیده
Electrical discharging machining (EDM) has become an outstanding approach in the field of metal cutting especially for conductive metals. It’s very difficult to cut the conducting metals with the aid of traditional machining. The main object of the present work has to investigate the effects of various EDM input parameters like pulse on time (Ton) pulse off time (TOFF) as well as the influence of different tool geometry on Material Removal Rate (MRR) Electrode tool geometry (ETG) peak current (A), flushing and pressure (P). Five basic input parameters were planned according to different levels as per the L16 orthogonal array. Multi-objective optimization technique of desirability approach and the significance of each parameter was analyzed by Analysis Of Variance (ANOVA).Fuzzy Logic Model (FLM) also used to better understand the input and output responses. It was found that rectangular tool geometry for cooper electrode emerged successful to get optimize results for MRR. Desirability approach and ANOVA for the comparison showed that current is the most influencing factor followed by pulse on time pulse off time.FLM tests were carried out to show closer relationship with experimental results.
