CHARACTERISTIC OF INTERACTION OF ABRASIVE GRANULA WITH DETAILS SURFACE IN VIBTRATION PROCESSING

English abstract

In this work, an overview of vibration processing was carried out. The vibrating process of machining parts is essential in ensuring the quality of machine-building products. The high-performance finishing method, one of which is vibratory, includes high-performance methods for cleaning, grinding and reinforcing machining of parts. Variety of processes of vibration processing give justification in the study of such basic patterns of vibration treatment method as the performance and quality of the treated surface, the characteristics of the interaction of the abrasive granules with the workpiece surface of the workpiece. The analysis of all ways of increasing the intensity. This is achieved through the simultaneous action on the working environment of two or more types of energy, or the additional movements of the parts being processed. The energy level of the work environment can be increased by providing additional movement to the vibrating chamber. This idea is the basis of the development of new processes of vibration-centrifugal processing (VCP) and equipment for its implementation. The schemes of interaction of the abrasive granule with the surface of the part under vibration and vibration-centrifugal treatment are considered. Process analysis is based on the nature of the interaction of the abrasive pellet with the surface of the workpiece. The whole process of forming roughness at the VCP was divided into certain stages. The characteristics of these steps and the change in these characteristics were used to describe the various schemes of the processes of interaction of the abrasive granule with the surface of the workpiece. The variety of process circuits determines the type of circulation of the abrasive medium. The proposed models reveal the physical nature of the interaction of the granules with the surface of the workpiece. The simultaneous action of vibration, centrifugal and rotational forces on the abrasive pellet increases the volume, and therefore the weight of the filtered microstrip, changes the nature of the flow of the bulk abrasive medium, which provides an increase in the intensity of the VCP and increases its technological capabilities.
