“…We noticed that this varied considerably, i.e., from 1.16-16.2 min. Although some of these processing times were quite short, this was due to the fact that the working regimes used in the current study were much more intense than those presented in the literature (up to three times) [16,[20][21][22]. The results showed a decrease in the processing time of stainless steel (up to 44% for the most intense working regime) when the mineral oil was replaced by edible oils.…”

“…A study conducted by Valaki et al [20] highlighted increased MRR (with 38%) and similar SR and SH compared to those obtained with kerosene. Singaravel et al [21] recently reported that vegetable oils (sunflower oil, canola oil and Jatropha curcas oil) showed similar dielectric properties and erosion mechanisms compared to kerosene when they were used for the electric discharge machining of a titanium alloy (Ti6Al4V), also providing a cleaner and safer machining environment. Das et al [22] also carried out a study on Jatropha curcas oil, canola oil and neem oil as alternatives to conventional kerosene for EDM of Ti6Al4V alloy.…”

One main drawback of electrical discharge machining (EDM) is related to the dielectric fluid, since it impacts both the environment and operator health and safety. To resolve these issues, recent research has demonstrated the technical feasibility and qualitative performance of vegetable oils as substitutes for hydrocarbon-based dielectric and synthetic oils in EDM. However, due to the higher content of unsaturated fatty acids, vegetable oils lose their stability, due to several factors such as heating or exposure to light or oxygen. The present study is a first attempt to analyze the extent to which the physic-chemical properties of vegetable oils change during EDM processing. Refractive index, dynamic viscosity and spectra analyses were conducted for sunflower and soybean oils. The results revealed that, under the applied processing conditions, no structural changes occurred. These findings are very promising from the perspective of EDM sustainability.

“…The average surface roughness observed by the Singaravel B et.al [40] was in the average range of 5.06 µm. They tested and concluded that the vegetable oil does not function as the dielectric medium in few cases and enhances the surface roughness comparative to the connectional dielectric medium.…”

The Micro EDM is the most suitable machining process in the miniaturization of products at present era. The attainment of close precision is the primary obligation in miniaturization or micromachining. Especially in machining of hard-to-cut materials like titanium alloy. Such alloys are applied in several cutting-edge high-quit applications due to extraordinary properties. Current work presents an exploratory analysis of novel Maglev EDM while machining of commercially used pure titanium alloy (CP-TI). The work outlook is to establish the viability of novel Maglev EDM by comparing the with similar range of micro EDM. The pure DC power is employed with the conjunction of Maglev lucidity to refine the shortcomings of the conventional micro EDM. The novel technology deals with prime concerns of conventional micro EDM and cracked deficiencies like delay response of mechanical actuator and a servo mechanism. The Novel technology uses the logical arrangement of permanent and electromagnet to dealt with inadequacies like short-circuiting and arcing. The results of state of art novel technology proclaimed the improved Material removal rate (MRR), which are lying in the average range of 76.6 µgm/min, whereas the specific energy and surface roughness are observed 33.4 Joule/ microgram and 4.3 µm respectively.

“…The usage of jojoba oil with the addition of nanoparticles in Ti-6Al-4V alloy hard turning was investigated by Gaurav et al [ 172 ] where conclusions were made that jojoba oil showed promising results in cutting force, surface roughness and tool wear improvements. Singaravel et al [ 163 ] investigated the use of vegetable oils such as sunflower, canola, and jatropha oils as dielectric machining fluids in titanium alloy EDM machining. Conclusion was made that vegetable oil was suitable replacement for conventional dielectric fluids with similar properties.…”

This paper reviews recent progress and applications of usage of cutting fluids in conventional machining processes. In addition to reviewing the various conventional and advanced cooling techniques during machining, the paper also discusses the use of minimum quantity lubrication (MQL) in several types on metals such as steel, aluminum, alloy, and titanium alloys. Due to the toxicity of conventional cutting fluid resulting in ecological problems, the demand for environmentally friendly cutting fluid is rising. Therefore, natural vegetable oil is chosen as potential replacement as an environmentally friendly cutting fluid which fulfills the important aspects of biodegradability and sustainability. Application of vegetable oil-based cutting fluids under MQL techniques are also discussed. Moreover, the potential of palm oil as biodegradable and environmentally friendly natural vegetable oil-based metal-working fluids in MQL are reviewed.
