Investigation of the Effect of Single Abrasive Grain Cutting Factors on Trace Microrelief on the Workpiece Surface Using Finite Element Modeling

A problem is formulated to investigate the influence of various factors of a single grain cutting process on the formed microrelief of the grain trace on the workpiece surface, such as the grain shape and cutting depth. Based on finite element modeling in the ANSYS finite element analysis software system in the Workbench environment of the interaction of abrasive grain with the workpiece, studies were carried out and the values of the geometric parameters of the microrelief of grain trace on the workpiece surface were obtained: depth, width, and mark area in the cross section, as well as the width, height, and area of the left and right piles in cross section. In addition to the geometric characteristics, the coefficient of material pushed into heaps was determined. The research methodology used made it possible to obtain the geometric characteristics of the microrelief of the trace from the abrasive grain and to determine their dependence on the cutting process factors: the abrasive grain shape and the depth of its penetration into the workpiece.
