| Sumario: | This paper considers the possibility of increasing the efficiency of the blade processing process by reducing the cutting forces during end milling by using a modified cutting fluid, which is based on a water-miscible cutting fluid. The conditions for the effective use of modified coolant in the processing of stainless steels were determined, as a result of which there is a decrease in cutting forces, and therefore a decrease in vibrations, which contributes to an increase in the quality of manufactured products. A decrease in cutting forces is associated with the presence in the modified cutting fluid of oleic acid containing surfactants, which form a dense lubricating film on the surface of the cutting tool. When mixing oleic acid in a water-miscible cutting fluid, a special soap solution is additionally used, which significantly improves the solubility, however, over time, oleic acid is separated from the total volume and tends to the surface. To ensure the homogeneity of the medium, a special device has been developed that allows continuous mixing of the compositions, due to the presence of impellers with a differently oriented arrangement of blades. To save lubricant, in the process of research, the technology of minimum quantity lubrication (MQL) was applied, using the Noga Minicool device, which allows portionwise (dosed) supply of lubricant to the cutting zone. |
