Analysis of existing approaches for describing the parameters of single sections during grinding

Abstract

Abstract The paper presents an analysis of various approaches to the formation of an abrasive grain trace in the process of finishing abrasive processing. It is noted that the trace of abrasive grain has a significant impact on the working conditions of the tool and the output parameters of the process. It is established that in the process of interaction of abrasive grains and the processed material, sections can be formed both in the form of a comma and in the form of a segment, which cannot be obtained in real conditions of the processing. It is shown that such an approach to all types and modes of grinding can lead to significant errors in the calculations and, as a result, an incorrect assessment of the influence of processing modes on the technological parameters of the grinding process. The study shows the need to obtain analytical dependencies for calculating the size of individual sections when changing the distances between the contacting grains of the abrasive tool in a wide range.
