The Main Ways to Control the Efficiency of Vibration Abrasive Processing

Abstract

The paper considers the main factors affecting the stability of the technological operation of vibration abrasive processing. The main ways of increasing the efficiency of processing by controlling its stability are revealed. The scheme of adaptive control of the process of vi-broabrasive machining is proposed according to the criterion of stability of the volume of loading of the working chamber, as one of the main factors that determine the stability of the cutting ability of the working medium (tool). The work substantiates the relevance of increasing the efficiency of vibration processing, as one of the promising methods of finishing. As a criterion of efficiency, the processing time was taken to ensure the specified quality indicators of the processed parts. Taking into account the peculiarities of vibroabrasive processing, three options for determining the minimum required processing time are proposed. In order to identify ways to increase the efficiency of processing, the analysis of the structure of the technological system was carried out, the classification of its elements was made. Based on the results of the analysis, it was concluded that a necessary condition for increasing the efficiency of processing is to ensure the stability of the parameters of the technological operation. In this regard, the main factors influencing the stability of the technological operation of vibration abrasive processing using the Ishikawa diagram are highlighted. The paper also presents the results of experimental studies of the influence of the volume of loading the working chamber on the cutting ability of the tool (working environment). Based on the results of theoretical and experimental studies, the main ways of increasing the efficiency of processing, including by controlling its stability, have been determined. The scheme of adaptive control of the process of vibroabrasive processing according to the criterion of stability of the volume of loading of the working chamber, as one of the main factors determining the stability of the cutting ability of the working medium (tool), is proposed.
