“…If we analyze the cooling fluids we find that they are of several types: aqueous solutions of electrolytes, hydrophilic soaps, corrosion inhibitors that use trisodium phosphate and soluble glass, oil-water emulsions, activated emulsions formed from water, active capillary substances and mineral oil emulsify, [10]. When preparing water-based emulsions, a softened water is used, the preparation is done by mechanically stirring the oil-water mixture by introducing the oil into the water.…”

An efficient MQL system (Minimal Quantity Lubrification) ensures the proper cooling of the various moving parts, resulting in the cutting process on the machine tools. The introduction of MQL systems responds to the growing demand in the industry with a whole host of real benefits. The geometry of the nozzle influences the flow parameters of the coolant; these parameters can also be influenced by the nature of the fluid or liquids used. The nozzle of the cooling system has a convergent-divergent geometry, the dispersion of the fluid in the areas to be processed being better. A high temperature in the working area above a certain critical value can be harmful to the quality of the surface and can have some negative influences on the life of the cutting tool. MQL-type cooling systems combine different cooling fluids to achieve better cooling and lubrication of the cutting area. Following the simulations performed, the coolant speeds depend on the length of the analyzed nozzle, we can see that the speed has a lower value in the initial section of the nozzle which increases at the nozzle outlet. After exiting the convergence-divergence nozzle, the fluid jet velocity decreases in proportion to the fluid jet length, the simulation of these phenomena can optimize the geometry for the chosen purpose. The present paper aims to analyze the types of coolants and their correct choice, temperature control resulting from the cutting process is achieved due to the correct distribution of cooling fluids in the processing area, optimization can be achieved through computer simulation.

“…The first is the mixing chamber, where the compressed air and oil are mixed; and the second is the nozzle's tip where the pressurised mixture is sprayed out toward cutting zones. MQL mechanisms afford many advantages such as maximising the volume of cooling liquids, controlling the mixing rates of air and oil, and precise spray direction using less mist [38].…”

Cooling systems in standard machining operations play an essential role in achieving the quality and performance required in operational outcomes. Most machining operations, and especially those dealing with refractory materials such as nickel, cobalt, and titanium-based alloys, cannot be conducted efficiently without the application of cooling. Cooling nozzles are important elements of cooling systems and control the flow rates of coolants as well as their direction. The design of the nozzle may significantly influence the efficiency of cooling systems, where high coolant consumption is one of their main ecological and economic drawbacks and poor nozzle design may result in the dissipation of coolant in an inefficient manner. This paper reviews state-of-the-art cooling systems used for machining, with an emphasis on the designs and applications of cooling nozzles used for grinding, milling, and turning operations. The first part of the paper considersrecent publications concerning common types of cooling systems as well as the nozzle designs and applications used, and also summarises the advantages and disadvantages of each system. The second part briefly discusses important research studies of the design, location and orientation of cooling nozzles. Finally, conclusions are drawn that represent the most significant results and findings of this review, the main objective of which is to fill the research gap identified with regard to the development of cooling and lubrication nozzles and their applications during grinding, milling, and turning processes.

In practice, different cutting processes are encountered, each process having different characteristics. Due to the existing friction forces between the workpiece and the cutting tool, a significant amount of heat is generated. This amount of heat can be determined by experimental measurements. With the help of the SolidWorks program, the geometric element that must be studied can be made, so that later it can be studied from the point of view of the thermal behaviors following the processing. We will take into account the different critical areas that may occur and that may materialize through areas where the final surface is not compliant. This paper aims to study the way in which the temperature is propagated in the workpiece, so that the phenomenon can be understood and determined how this excessive heat can be removed from the cutting area.
