Surface finish has an essential role in superior performance of machined products which becomes crucial for sophisticated applications like invasive biomedical implants and aerospace components. Ti6Al4V is popular in these applications due to its exceptional characteristics of weight-to-strength ratio. However, Ti6Al4V is a difficult-to-cut material; therefore, non-traditional cutting techniques especially, electric discharge machining (EDM), are widely adopted for Ti6Al4V cutting. The engagement of nano-powders are used to upsurge the cutting rate and surface quality. Among the different powders, a novel nano-powder additive, i.e., graphene, has not been tested in EDM of Ti6Al4V. Therefore, the potential of nano-graphene is comprehensively investigated herein for roughness perspective in EDM of Ti-alloy. The experimental design is based on Taguchi L18 orthogonal framework which includes six EDM parameters. The experimental findings are thoroughly discussed with statistical tests and physical evidence. The surface quality achieved with an aluminum electrode was found best amongst its competitors, whereas the worst surface asperities were noticed when brass electrode was used under graphene mixed dielectric. Moreover, it is conceived that the positive tool polarity provides lower roughness for all types of electrodes. Furthermore, optimal settings have been developed that warrant a reduction of 61.4% in the machined specimen’s roughness compared to the average roughness value recorded during the experimentation.

Due to its high corrosion resistance and low density, it is tedious to machine high strength materials such as titanium alloy for the manufacture of engineering products related to aerospace, automobiles, and medical applications. In this study, an attempt was made to consider the impact of tool electrodes in the electrical discharge machining method for successful machinability of titanium alloy. High temperatures are used during electrical discharge machining to melt and vaporise the hard titanium alloy. In the current work, an EDM machining method was used to machine a Ti-6Al-2Sn-4Zr-2Mo alloy while using the input parameters of pulse on time, voltage, and current as process parameters. The experiments were carried out based on the workpiece, and surface morphology was performed on the workpiece surface. The process parameters were optimised using the Multi-Response Grey Relation Analysis method, and a major effects plot was created to see how the factors affected the MRR and surface roughness. Surface finish and MRR have been discovered to be directly correlated with discharge current. These are the best process parameters for machining pulse on time (150 s), voltage (60 V), and discharge current (16 A).

“…Despite the extensive use of CVD for the synthesis of nano materials, the effects of process parameters on the size and properties of nano materials remain poorly understood [6]. Previous studies have mainly focused on the effects of individual parameters, such as temperature or pressure, on the size and properties of nano materials [7][8][9][10][11]. However, the interplay between different process parameters and their combined effects on the size and properties of nano materials have not been systematically investigated.…”

In recent years, the development of nano materials has garnered significant attention due to their unique properties and potential applications in various fields. However, the influence of process parameters on the size and properties of these materials remains a complex and largely unexplored area of research. In this study, we systematically investigate the effects of process parameters such as temperature, pressure, and reaction time on the size and properties of nano materials synthesized via a chemical vapor deposition (CVD) method. Using advanced characterization techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD), we analyze the morphology, size distribution, and crystal structure of the synthesized nano materials. Our results reveal a strong correlation between the process parameters and the size of the nano materials, with temperature and pressure being the most influential factors. Furthermore, we observe a significant impact of the process parameters on the mechanical, thermal, and electrical properties of the nano materials. These findings provide valuable insights into the optimization of process parameters for the synthesis of nano materials with tailored properties, paving the way for their application in diverse fields such as electronics, energy storage, and catalysis. Our study contributes to the fundamental understanding of the relationship between process parameters and the properties of nano materials, offering a comprehensive framework for the design and synthesis of nano materials with desired characteristics.
