Investigation of the effectiveness of the method of finishing the inner cylindrical surfaces of machine parts with a free abrasive using the effect of vibration cavitation

Abstract

Finishing of high-precision machine parts is one of the most labor-intensive operations in the technological process. This process becomes especially difficult when it is necessary to ensure a high-quality surface in hard-to-reach places for parts made of materials with special physical and mechanical properties. In such cases, the solution to the problem may be the use of methods of processing with free abrasive particles. Based on the foregoing, it can be concluded that improving the efficiency of methods for processing parts with a free abrasive is the most important task for researchers in the field of mechanical engineering technology.The authors of the article carried out a series of experiments on finishing the inner cylindrical surfaces of machine parts of the “sleeve” type with a free abrasive using the effect of vibration cavitation. The study is of an applied nature - according to the design documentation for the product, it is necessary to achieve a roughness in the inner surface of Ra 0.80.
