“…For instance components made of NITINOL s nickel-titanium alloy, Stellite s and Vitallium s Co-Cr alloys, molybdenum alloys and tungsten alloys are usually manufactured by casting and sintering techniques or machined by non-traditional techniques such as electro-discharge machining (EDM), electro-chemical machining (ECM), laser beam machining (LBM) or ion beam machining (IBM), etc. [49].…”

a b s t r a c tMachining difficult-to-machine materials such as alloys used in aerospace, nuclear and medical industries are usually accompanied with low productivity, poor surface quality and short tool life. Despite the broad use of the term difficult-to-machine or hard-to-cut materials, the area of these types of materials and their properties are not clear yet. On the other hand, using cutting fluids is a common technique for improving machinability and has been acknowledged since early 20th. However, the environmental and health hazards associated with the use of conventional cutting fluids together with developing governmental regulations have resulted in increasing machining costs. The aim of this paper is to review and identify the materials known as difficult-to-machine and their properties. In addition, different cutting fluids are reviewed and major health and environmental concerns about their usage in material cutting industries are defined. Finally, advances in reducing and/or eliminating the use of conventional cutting fluids are reviewed and discussed.

Micro-electrical discharge machining is an indispensable tool to manufacture the component or parts of components at the micro-level with reasonable accuracy and precision. This article reports a comprehensive overview of micro-EDM along with their recent trends and key challenges. The sparking phenomenon, physical principle of material removal, process capabilities and flexibility with the other machining process are discussed in the initial part of the paper. Major development issues associated with nano-EDM are reviewed, and suggested solutions are proposed. Research and technology gaps enabling the transition from micro-EDM to nano-EDM are examined. The impact of discharge power technology and dielectric circulation is explored. Moreover, this review article explores the sustainability of the system (micro-EDM) through green manufacturing. A state-of-the-art has been studied in various aspects of micro-EDM. The promising future research scope is also noted in micro-EDM as well as in nano-EDM based on the electrical discharge.

Growing demand for Stellite 6 alloys due to its attractive properties such as superior strength, toughness, wear resistance, fracture resistant characteristics, and their exceptional resistance to corrosion has made them applicable in industrial as well as commercial applications, such as aerospace industries, nuclear waste storage, automobile industries and surgical implantation. However, in spite of these applications, automotive part manufacturers mainly (Bearing Materials) are looking for a comprehensive study, such as mechanics of friction and the relationship between friction and wear. Hence in this paper, an attempt has been made to study the tribological behavior such as wear characterization and surface roughness of age hardened Stellite 6 alloys. The main objective of the research is to determine the favorable tribological conditions for improving wear resistant properties and surface roughness on age hardened Stellite 6 alloys. Hence two body wear study and surface roughness study during Wire Electric Discharge Machining (WEDM) of age hardened Stellite 6 alloys based on Analysis of Variance (ANOVA), Taguchi's Design of Experiment (TDOE), Response Surface Methodology(RSM) and Desirability Functional Analysis (DFA) have been used to achieve this goal. From the study it is observed that optimum values for improving hardness, wear and surface roughness values can be easily achieved with less time and cost by adopting the said techniques. •From microstructural observation, as the peak current increases there is larger amount of dendritic carbides and cracking of carbides due to high plastic deformation resulting in thermal softening of Stellite 6 alloy during wire electric discharge machining resulting in better surface roughness values. The second-order model for hardness, wear and surface roughness using response surface methodology can be adopted for predicting for hardness, wear and surface roughness in any experimental domain.
