Ni alloys have managed to cover wide range of applications such as automotive industries, oil gas industries, and aerospace industries. However, these alloys impose challenges while using conventional machining technologies. On the other hand, Micro-Electro-Discharge machining (micro-EDM) is a nonconventional machining method that uses controlled sparks energy to remove material irrespective of...

Abstract NetZero advancements for the manufacturing industry are aspiring precision machining of difficult-to-cut materials with a high degree accuracy, particularly Ni-based super alloys while meeting climate protocols. The applications and properties foregoing warrant usage electric discharge (EDM) technique. However, given rising scarcity resources, there is compelling need to make this proc...

Electric discharge machining (EDM) is a ‘newer technology utilized to machine hard metals, alloys, composites and ceramics. This paper reports the experimental investigation carried out on EDM to study the effects of machining parameters such as pulsed current on material removal rate, depth of cut, overcut, tool wear (net weight lost) and hardness on En-31 tool steel The work material was elec...

The growing dominance in terms of industrial applications has helped polymer-based composite materials conquering new markets relentlessly. But the presence fibrous residuals and abrasive particles as reinforcement polymer matrix composites (PMCs) affects output quality characteristics (OQCs) microdrilling operations. OQC aims at reducing overcuts momentous material removal rate (MRR). In such ...

Titanium alloy is widely used in modern automobile industries due to its higher strength with corrosion resistance. Such materials can be effectively machined using unconventional machining processes, especially the electro-chemical micro (ECMM) process. It important enhance process by investigating effects of electrolytes and parameters ECMM. The presented work describes influence three differ...

Abstract Frontal ablation, the combination of submarine melting and iceberg calving, changes geometry a glacier's terminus, influencing glacier dynamics, fate upwelling plumes distribution meltwater input into ocean. Directly observing frontal ablation terminus morphology below waterline is difficult, however, limiting our understanding these coupled ice–ocean processes. To investigate evolutio...

background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

The use of stainless steel 316L (SS 316L) in the medical, marine, aerospace, bio-medical, and automobile sectors increases rapidly. Electrochemical micro-machining (ECMM) is appropriate method for machining SS due to its burr-free surface, no residual stress, high precision. However, some limitations are found using strong electrolytes, such as HCl, H2SO4, KOH, NaNO3, NaCl, which reportedly fac...
