Summary: This study investigated the influence of graphite tool electrode grain size on the machining of Hastelloy C-22. It was found that graphite with larger grain size improved process efficiency but had higher relative wear of the tool electrode. Smaller grain size graphite resulted in lower surface roughness. The discharge current, pulse duration, and time interval were identified as important parameters affecting machining quality.

Summary: Electrical discharge machining (EDM) is an essential unconventional electrothermal machining process that plays a crucial role in machining the contour profiles of hard materials in modern production industries. By replacing liquid dielectric fluid with gas and a small amount of liquid mixed with gas, green machining processes can be encouraged. Various gases and gas mist have been used as working fluids in dry and near-dry EDM, and extensive literature surveys have illustrated the research context, different dielectric fluids, sustainable and innovative developments, process parameters, machining characteristics, and optimization techniques. Future research opportunities in both dry and near-dry EDM have also been summarized to promote eco-friendly EDM research activities.

Summary: In this study, a near-dry electrical discharge machining (NDEDM) process using oil-mist as the working fluid was conducted to investigate the machining characteristics. The Box-Behnken method was employed to analyze the effects of oil flow rate, air pressure, spark current, and pulse width on gas emission concentration, material removal rate, and surface roughness. The TOPSIS technique was used to determine the optimal machining parameters. The study also examined the microstructure of the machined surfaces using SEM and EDS analysis, achieving desirable results with specific parameter settings.

Summary: The study focused on improving the mechanical, physical and interfacial properties of aluminum alloys by adding silicon carbide particles and investigating the machinability of the composite using wire-EDM. The optimized wire-EDM settings resulted in MRR of 65.21mg/min and 62.41mg/min for samples with 4% and 8% SiCp, while the influence of reinforcing SiCp up to 8% on MRR was marginal. The statistical model developed for predicting MRR using linear regression showed a predicting accuracy of 73.65% and can be useful for predicting MRR for different process parameter settings.

Summary: The research compared the wire wear ratio, material removal rate, and surface roughness of cryogenic cooled near dry wire-cut electrical discharge machining (NDWEDM) with the existing NDWEDM process. It was found that cryogenic cooled NDWEDM reduces wire wear ratio, increases material removal rate, and decreases surface roughness compared to the existing NDWEDM process, due to the increase in electric conductivity and effective spark strengths by cryogenic cooled wire.

Summary: The study found that cutting parallel to the fibre direction resulted in a higher material removal rate compared to cutting perpendicular to the fibers, but also led to larger kerf widths and poorer surface roughness. Additionally, the cutting direction also affected the severity of defects on the workpiece surface.

Summary: Traditional liquid electric discharge machining emits a large amount of carbon, while electric discharge machining in gas, or dry EDM, offers possibilities for sustainable development. This study focuses on the servo control of dry EDM to improve discharge stability and machining efficiency. By comparing different control strategies, significant improvements were obtained in terms of discharge ratio and machining efficiency. The study also analyzed the servo characteristics under different gas media and proposed an optimization scheme. Experimental results confirmed the effectiveness of the servo strategy and the matching characteristics of different media and servos in EDM.

Summary: A low frequency vibration platform was developed to improve the performance of EDM by assisting in debris removal and transportation of dielectric. The peak current was found to be the most significant parameter affecting performance, while a vibration frequency below 100 Hz did not lead to satisfactory improvement in material removal rate and tool wear rate under selected machining conditions.
