This work represents a feasibility study for the newly proposed vegetable oil based green dielectric fluids, biodielectric1 (BD1) and biodielectric2 (BD2) for Electric discharge machining (EDM). Comparative analyses for BD1, BD2 and kerosene have been studied to assess the performance in terms of material removal Rate (MRR), electrode wear rate (EWR) and relative wear ratio (RWR) for P20+ cold worked plastic injection mould steel using electrolytic grade copper electrode. Current, Gap voltage, Pulse on time (T on ) andPulse off time (T off ), have been chosen as input parameters and one variable at a time approach has been used for designing experimental plan for investigating feasibility of the newly suggested fluids. The results obtained show that performance of the newly suggested biodielectrics BD1 and BD2 are better than commercially used hydrocarbon based dielectric i.e. Kerosene, for MRR and RWR. ANOVA results indicated that current is the most influencing parameter for MRR and EWR, while T on is the most significant parameter for RWR. Under the influence of current, BD1 and BD2 produced 38% and Downloaded by [New York University] at 00:10 02 August 2015 2165 % improvement in MRR respectively. Moreover, BD1 and BD2 resulted 30% higher and 7% lower RWR, respectively under the influence of T on.

“…However, it has a series of technological problems such as high energy consumption, relatively low processing efficiency and poor processing environment. Jagdeep [12] and other scholars [13][14][15][16][17] have conducted in-depth research in the field of green EDM, analysis of machining mechanisms and improvement of the machining environment. Giuseppe et al [18] defined a sustainability index on energy consumption and have applied it to a micro-electrical discharge machining (micro-EDM) process in drilling operations.…”

In recent years, the energy problem has caused widespread concern in the manufacturing industry. The energy consumption in traditional turning and milling processes has been widely studied. However, there are few studies on the energy consumption of the EDM (Electric Discharge Machining) process, which is also widely used. This paper proposed a modeling method for the energy consumption model of EDM based on the discharge between electrodes. The proposed model is composed of processing energy consumption caused by electrode-to-electrode discharge and no-load energy consumption of the machine tool. Based on the discharge principle of EDM and the relationship between EDM machining parameters and MRR (Material Removal Rate), an energy consumption model for EDM machining is established. In this paper, validation experiments are designed for important machining parameters, and the prediction accuracy of the theoretical model established in this paper is higher than 96%. The energy efficiency in electric machining is also analyzed, and the influence relationship between energy consumption and machining parameters is revealed, which can effectively reduce the energy consumption of electric spark punching.

Nonconventional or advanced machining processes such as electric discharge machining, electrochemical machining, abrasive water jet machining, and laser beam machining have been widely used as a viable alternate to the conventional processes to manufacture high-quality engineered parts having certain typical features. In spite of their special features, wider acceptance, and use, they suffer from certain inherent limitations with regard to sustainability such as high consumption of energy and resources; generation of toxic liquid, gases, and solid wastes; risk for health and safety; air pollution; generation of waste and its disposal problems; and workpiece contamination and thermal damage to the parts being produced. It is found that these factors all adversely affect the environment to a certain extent. Innovative sustainable techniques such as dry, near-dry, and green electric discharge machining; green and hybrid electrochemical machining; ice-jet machining; and eco- and underwater laser beam machining, etc. have been developed to address sustainability challenges and greatly benefited with improvements in quality, productivity, and sustainability. This review article first introduces four major nonconventional machining processes, discusses their inherent sustainability issues and challenges, and presents state-of-the-art review of the work conducted using sustainable innovative techniques and strategies with an aim to encourage academics, researchers, and engineers for research and developments in order to establish the field further. The literature review offered in this article is based on over 80 articles published from 1975 to 2017. Finally, the article ends up with concluding remarks and recommending possible avenues to stimulate future research.
