The efficiency improving of abrasive flow machining on managing of the life cycle factors of media

The article proposes the approach in which a set of factors and response functions is determined for each stage of the life cycle of the working medium for abrasive flow machining treatment. The response functions in turn in the next stage become factors (initial data). The analysis of publications has shown that in the literature there is no systematized description of the factors of the technological process of abrasive flow machining at different stages of the life cycle. An attempt is made to systematize the variables of this technology and to establish their interrelation through the stages of the life cycle of the working media as a finishing tool. The authors describe the life cycle of the working medium for abrasive flow machining. The life cycle includes five stages, divided into thirteen stages. On the basis of the analysis of the world experience, a set of factors is proposed for each stage enabling to give a characteristic of the workpiece, working medium, processing modes, as well as contact interactions between the abrasive grain and the surface to be finished. The authors made a description of the peculiarities of the stage of manufacturing the stage of the experimental batch of the life cycle of the working environment, in which features of the technology of its production are disclosed. The approach described in the article makes it possible to improve the efficiency of abrasive flow machining by reducing the costs of preparing the production and operating the working media. This fact is especially important for the production of rocket and space technology, characterized by a wide range of parts with different types of surfaces that require finishing operations.
