Study of the Microrelief Obtained During Single Abrasive Grain Cutting

Abstract

AbstractThe paper briefly reviews the literature on the microrelief obtained during single abrasive grain cutting. The review presents various methods of experimental research, including the building of topography by removing points from an experimentally obtained mark, finite element modeling of marks from a single abrasive grain, a comparison of a modeled mark with an experimentally obtained mark, and the workpiece surface relief in the contact zone after machining with grinding wheels of various grain sizes. We proposed a proprietary methodology for conducting a micro-cutting experiment, which includes an experiment on obtaining marks on a specially equipped surface-grinding machine and microscopic examination of marks for the presence of barbs and pile using a microscope with special software allowing for topographies to be built using images from the workpiece surface. We considered a selection of marks on the experimental sample necessary to form the research results. During the experiment, we found a dependence reflecting the nature of formations (barbs and piles) at various mark depths and lengths. A brief conclusion is made on the possible causes of the appearance of these formations; future research work is planned in this area.KeywordsMicro-cuttingAbrasive grainMicroreliefGrindingTopography
