Abstract
Introduction. Treating small-sized parts having internal channels is a complex technological task that can be solved using dispersed grinding materials. The required surface quality of the internal channels can be achieved by using centrifugal planetary treatment technology with the correct choice of technological modes. It is necessary to develop a theoretical framework for this technology.
Aim of the Study. The study is aimed at substantiating theoretically the possibilities of centrifugal planetary surface treatment of small-sized channels based on the determination of contact interaction parameters upon a sliding impact of the working material.
Materials and Methods. To determine the range of equipment technological characteristics, there was used the developed program “Channel”, the initial data for which were calculated using computer simulation of contact interaction in the software package ANSYS WORK-BENCH. Experimental studies were carried out on the installation D7H.650.00.00. There were used the samples of small-sized brass parts DKRNT 30 ND L63 GOST 2060-2006 with silver electroplated coating. CHRONITAL – CAST Stainless Steel Shot by the firm Vulkan Inox Gmbh (Germany) was used as working material.
Results. The calculation results was analyzed in the program ANSYS that made it possible to determine the range of working material speed at which deformation of the part base was within the normal range. The calculated speed range was used as the initial data for calculating the technological factors of processing in the program “Channel” that provided the necessary data for the theoretical calculation of surface roughness. To determine the experimental roughness values, there were carried out the studies, which allowed us to found an empirical relationship. There has been shown the convergence between the results of theoretical and experimental studies.
Discussion and Conclusion. For the technological preparation of manufacturing, there have been theoretically described and experimentally confirmed the relationships between the roughness parameters of the coated inner surface under treating and the technological modes of centrifugal planetary treatment. Based on the study results, there has been developed a method for treating internal channels of parts with complex profile surfaces. This method is aimed at increasing their manufacturing efficiency while ensuring the required surface quality. The proposed method is the basis for the technological preparation of manufacturing parts with internal surfaces having a silver electroplated coating. Further research in this area suggests expanding the range of coating materials, the hardness of which correlates differently with the hardness of the base material.
