Background. The object of the study is cutting tool cooling at blade machining in the field of mechanical engineering by means of cooled ionized air supply to the cutting zone. The subjects of the study are processes of cutting tool cooling, ionization in swirling air flows and the mechanism of interaction of ionized air with the machining surface. The aim of the work is to study the efficiency of using cooled ionized air for cooling at blade machining of structural materials and to create a compact and easy-to-use device for equipping the machinery.
Materials and methods. The processes were researched by the method of experimental analysis.
Results. The work introduces a developed system of cooled ionized air supply for cutting tool cooling at structural materials machining investigates ionization processes in swirling air flows and considers the mechanism of interaction of ionized air with the machining surface. The article also shows advantages of using cooled ionized air for blade machining of structural materials and describes the system of cutting tool and cutting zone cooling with cooled ionized air.
Conclusions. The obtained results show the possibility of effective use of cooled ionized air as lubricating-cooling technologies at blade machining of structural materials. Its usage reduces roughness and microhardness on the machining surface, increases cutting tool resistance, reduces the cost of processing and the environmental issues. The developed system using "InAir" cooled ionized air allows to supply the air for cutting tool and cutting zone cooling to the machining zone as a part of the technological equipment for processing of structural materials.
