Abstract

Background. At the stage of developing the technological process of turning a part, it is important to identify the processes that occur as a result of the impact of the tool on the workpiece. The stresses, pressures, forces and temperature deformations resulting from the action of the cutter mainly determine the properties of the part obtained as a result of processing. The most important step at the stage of technological development of a part is the modeling of the cutting process. Computer modeling allows you to fully simulate the turning process, take into account the parameters of the workpiece rotation, cutting modes, gravity and inertia of the workpiece during rotation, forced vibrations and self-oscillations, as well as the chip formation process. The purpose of the study is to develop a computer model for complex spatial movement of a cutting tool, which makes it possible to study the stress-strain and thermal state of the cutting process, chip formation conditions, predict the quality parameters of the surface layer, and also take into account the characteristics of the workpiece and the cutting tool, with the subsequent possibility of parameterizing the process. Materials and methods. The theoretical and experimental studies carried out in the work are based on the basic principles of cutting theory, materials science, and material resistance. The virtual simulation was carried out in the Ansys Workbench software package. Results. A computer model of the complex movement of a cutting tool and the destruction of a rotating workpiece with chip formation has been developed. Conclusions. The obtained results of the computer model of the turning and chip forming process are adequate to field studies of processing.
