In this paper, the effect of magnetic field on lubricating cooling liquids, which are used in the cutting process in manufacturing, was studied. We chose three different lubricating cooling liquids that are commonly used in local manufacturing factories to conduct the experiment. Three main properties of these lubricoolants, boiling point, kinematic viscosity, and density, were analysed after magnetizing them. The magnetization processes were conducted in two conditions of liquids. At the first stage, the authors magnetized the liquids in stationary conditions; at the second stage, they magnetized the flowing liquids and analysed the difference among all the obtained results. This article shows the results of the comparisons and analyses the magnetic field influence on different types of fluids. Moreover, the paper investigates the dependence of magnetic field strength on the influence of magnetic field on liquids. It was found that the examined three parameters of liquids were changed after magnetic field treatment. The finding of this research offered a simple approach to improve the lubricating and cooling process in machining details in manufacturing. ABSTRAK: Dalam makalah ini, pengaruh medan magnet pada cecair pendingin pelincir, yang digunakan dalam proses pemotongan dalam pembuatan, telah dikaji. Kami memilih tiga cecair penyejuk pelincir berbeza yang biasa digunakan di kilang pembuatan tempatan untuk menjalankan eksperimen. Tiga sifat utama pelincir ini seperti takat didih, kelikatan kinematik, dan ketumpatan dianalisis setelah memagnetkannya. Proses pembesaran dilakukan dalam dua keadaan cecair. Pada peringkat pertama, kami memagnetkan cecair dalam keadaan pegun dan membandingkan hasilnya; pada peringkat kedua, kami memagnetkan cecair semasa mengalir dan menganalisis perbezaan antara hasil yang diperoleh. Artikel menunjukkan hasil perbandingan ini dan menganalisis pengaruh medan magnet pada pelbagai jenis cecair. Lebih-lebih lagi, makalah ini meneliti pergantungan kekuatan medan magnet terhadap pengaruh medan magnet pada cecair. Didapati bahawa tiga parameter cecair yang diperiksa diubah setelah rawatan medan magnet. Penemuan penyelidikan ini menawarkan pendekatan mudah untuk meningkatkan proses pelinciran dan penyejukan dalam perincian mesin dalam pembuatan.

This paper presents a novel methodology of using cutting fluids to improve the material removal process in metal cutting. To this end, a set of orthogonal cutting experiments are conducted using various cutting fluids to calculate the chip shrinkage coefficient in the material removal process. Chip shrinkage coefficient has been focused on as an important factor that affects chip formation in the material removal process. Using cutting fluids under the influence of a static magnetic field in the metal cutting process is proposed as an innovative method to decrease the deformation that is emerged in the chip formation process while cutting cylindrical parts in lathes. Experiments showed that the application of cutting fluids under the influence of a static magnetic field decreased the shrinkage of the chip by up to 20 % in comparison to the conventional use of cutting fluids in turning cylindrical parts with HSS tools. Moreover, a mathematical model of the effect of boiling point and density of cutting fluids on tool flank wear has been developed in this paper. The obtained results present that the magnetized cutting fluids have an improved cooling capacity and they can be used as a modern cutting fluid in manufacturing.
