Influence of physical and chemical properties of cutting fluids on the cutting force of the cutting process

The problem of providing increased accuracy without sacrificing productivity is encountered in almost all machine-building enterprises. cutting fluids affect the entire process of blade processing: they remove heat from the surface of the cutting tool, form an additional surface between the surfaces of the cutting tool and the workpiece, and affect the juvenile surfaces of the workpiece by means of a wedging action. The positive effect of cutting fluids is achieved only if they are rationally chosen. Currently, the choice of technological environments is based on some legislative standards of the enterprise. The market for cutting fluid has a large number of brands, which makes the decision more difficult. Сutting fluids give only a qualitative assessment of their brands based on their functional actions. A similar problem of choosing a rational brand of cutting fluids was also encountered in the manufacture of the innovative «Fregat» and «Fregat-SB» accelerating units. During the processing of the structural materials previously mentioned, the impact of cutting fluids was evaluated using an experimental method. The equipment for the experiment was machining center. The methodology for the experiment included external turning at different cutting speeds and feeds of the cutting tool. Free-falling jet irrigation was chosen as the method of supplying the cutting fluids. The cutting forces were measured under the action of various cutting fluids. On the basis of the experiment, regression dependences of the physicochemical properties of cutting fluids on cutting conditions were compiled. Subsequently, according to the regression dependencies, it is possible to select the optimal brand of the cutting fluids, taking into account the cutting forces in various cutting modes.
