“…It is a complex task to show the impact of all process parameters on the performance criteria. In this work, the primary EDM electrical process parameters such as current, pulse duration/pulse on-time and pulse interval/pulse off-time are chosen based on their significant influence on machining performance characteristics [27,28]. Based on exploratory trial experiments and capacity of the machine setup, the appropriate range for process parameters was selected.…”

In this study, a newly engineered stir-cast LM13 aluminium alloy-based hybrid composite (5 wt% of TiC and 10 wt% of ZrB 2) is used as workpiece and its machinability investigation is carried out using EDM (electric discharge machining) drilling route with copper electrode. During experimentation, the process variables, namely current (I), pulse on-time (T on) and pulse off-time (T off), are varied and the output performance characteristics, viz. material removal rate (MRR), electrode wear rate (EWR) and dimensional accuracy, i.e. overcut (OC), are measured. The series of experiments (20 runs) are formulated through the adoption of response surface methodology (RSM)-based full-factorial central composite design. To recognize the correlation between the process variables and performance characteristics, a mathematical model is developed for each response. Subsequently, adequacy of the proposed models is verified using analysis of variance (ANOVA). Moreover, ANOVA is employed to identify the significantly influencing process parameters over the performance characteristics. From the analysis of results, it is inferred that the current has the most dominant effect on MRR and EWR, whereas OC is highly influenced by T on. Composite desirability function approach of RSM is utilized to find the optimum set of process parameters in order to satisfy the desired multi-performance characteristics (such as maximizing MRR, minimizing EWR and OC) for obtaining effective holes on hybrid LM13-10ZrB 2-5TiC composite. Finally, optimized results are validated with the experimental results to determine the competence of adopted desirability approach.

Metal matrix composites is a new expansion to cutting-edge materials having astounding properties like a weightless, high explicit quality and great consumption obstruction properties. These types of materials are highly desirable industries. Automobile and aerospace industries require materials that have good strength to weight ratio in order to achieve higher fuel efficiency. It is difficult to machine these types of new generation metal matrix composites with conventional machining techniques. For machining these types of composites now a day’s unconventional machining techniques like electrical discharge machining are used. This paper presents review of research work carried out by researchers in EDM on composites. This paper also considers the attribute trends of EDM machining.

Electrical discharge machining (EDM) is one of the earliest non-conventional method of manufacturing processes. This process based on thermoelectric energy between work piece and electrodeand they must have electrical conductivity to generate the spark. A spark generated between work piece and electrode, and removes the material from work piece through melting and vaporizing. EDM produced various types of products such as dies and moulds. EDM is used to manufacture the parts of aerospace, automotive industry and surgical components. The effect of the machining parameters on surface roughness, metal removal rateand tool wear rate are studied.
