“…Kegunaan beberapa minyak nabati telah dipelajari, seperti minyak kelapa, minyak kelapa sawit, minyak zaitun, minyak wijen. Minyak kelapa memiliki kinerja yang baik untuk digunakan sebagai cairan pedingin untuk stainless steel karena menghasilkan ketebalan yang seragam dan keausan pahat yang rendah dibandingkan dengan minyak yang lainnya [7]. Hasil tersebut menunjukkan bahwa minyak nabati memiliki potensi besar sebagai pengganti cairan pemotong untuk diaplikasikan pada proses pemesinan karena dapat menyelamatkan lingkungan.…”

Coolant is one of the factors that affects the quality of the workpiece. The selection of coolant is useful to lower the surface roughness of the workpiece. In addition, coolant should be easily degradable in the environment so that the environment is not polluted. Example coconut oil is an oil that can be degraded in the environment. This research is aimed to observe the influence of coconut oil for cooling to the surface roughness obtained during face milling process. In the experimental tests, conventional milling machine was used and the milling tests were performed under various machining parameters, namely spindle rotational speed was 360 and 490 rpm, feeding speed was 60 mm/min and 70mm/min. Based on the result, the surface for spindle rotational speed of 360 rpm and feeding speed 60 mm/min was more rough than one in spindle rotational speed of 360 rpm and feeding speed 70 mm/min. Besides, the surface roughness for spindle rotational speed of 490 rpm and feeding speed of 60 mm/min was also more rough than one in spindle 490 rpm and 70 mm/min.

“…Cutting fluids are usually indispensable to modern cutting processes, wherein the fluid is responsible for lubrication, cooling, chip removal, and other functions [1][2][3]. In broaching or other cutting applications, the mineral oil-based cutting fluid is largely used because of its acceptable lubrication and cooling effect.…”

With increasing environmental concerns, the substitution of mineral oil-based cutting fluid has become an urgent issue. Using vegetable soybean oil as base fluid, nanofluid cutting fluids (NFCFs) were prepared by adding different weight concentrations of nanographite particles (NGPs), and their penetration and lubrication performances were studied. A novel simulated tool-chip slit with micrometer-sized geometry was manufactured to evaluate and quantify the penetration rate of the NFCFs by image analysis approach. Moreover, a large number of comparative experiments on the closed-type broaching machine were carried out to compare the performance of the proposed NFCFs and a commercial cutting fluid in terms of cutting force, workpiece surface roughness, and metal chip. It is found that there is an optimal NGP concentration in NFCF for practical cutting applications. When the concentration of NGP is 0.4 wt%, the broaching process lubrication exhibits an ideal mixed lubricate state, resulting in minimal friction resistance, and thus, both the cutting force and chip curling angle reach their corresponding best values. Moreover, the proposed NGP-based vegetable-oil cutting fluid exhibits excellent environment-friendliness and low-cost consumption in the minimal quantity lubrication (MQL) method; this demonstrates its potential for replacing the traditional broaching cutting fluid.

“…Good cutting fluid must have properties like non-toxic, nonflammable, long term stability, high thermal conductivity and low viscosity to permit the chips washed away quickly from work-tool surface [6]. However, conventional cutting fluids make with mineral oil causes many environmental issues and also adversely affect the health of user [7]. These conventional cutting fluids also hamper the health of workers.…”

Machining hardened steels is always difficult because of its excessive heat generation. That is why, the application of cutting fluid in machining hardened steel is noted for eliminating defects triggered by the high cutting temperature. In this respect, the aim of this paper is to present a stable high volume carbon nanotube based nanofluid which will act as an efficient cutting fluid and perform better than conventional cutting fluid. To fulfill this purpose, the samples with different volumes of Carbon nanotubes were made and their stability was analyzed. Both the sedimentation and zeta potential analysis proved that the sample made with less than 0.4% volume CNTs shows higher stability. Conventional cutting fluid was made with oil mixed in water and compared its properties to all nano fluid samples. All the nano fluid samples showed higher thermal conductivity and lower viscosity than conventional cutting fluid. Furthermore, a milling operation on 42CrMo4 hardened steel material was performed without any fluid, with conventional (Aquatex 3180 oil based cutting fluid) and with nano fluid. Nano fluid was delivered internally to the cutting zone by using a specially designed liquid applicator. Maximum 29% reduction in cutting temperature, 34% reduction in surface roughness, 33% reduction in cutting force and 39% reduction in tool wear was obtained by using the 0.3 vol% nanofluid sample. So, it can be concluded that the 0.3% volume carbon nanotubes based cutting fluid is an appropriate choice to be used in machining hardened materials.
