Application of the finite element method to search for ways to optimize the temperature field when cutting with tools from the ВL group PCNB

Abstract

The intensification of the machine-building industry today is connected with the development of the latest methods of researching the processes of manufacturing machine parts and with the improvement of high-speed cutting processes. Metalworking processes with tools made of ultra-hard materials are increasingly being implemented in industry, which provide a significant increase in productivity, the quality of the machined surface and improvement of cutting modes with a blade tool. All these parameters are determined by many factors, namely the structural and geometrical elements of the cutting part, the material of the cutting tool, chip formation, the conditions of cooling the cutting edges, which further forms the conditions for choosing productive cutting modes. The choice of tool material is one of the most important parameters that ensures high productivity of the cutting process. Polycrystalline cubic boron nitride of the BL group for blade tools has become widely used. But during high-intensity processing processes, questions arise about the optimization of temperature fields in the processing zone. An even more difficult task is the study of high-speed processing processes, with the determination of temperature regimes, and technological processes, both in a scientific environment and directly in industrial production. Solving these problems can be done by modeling the working processes of cutting, in particular, using the finite element method, which will allow the construction of new models in thermobaric processes during cutting.
