Abstract

The mechanical wear is the main mechanism of abrasive grain wear during grinding. This mechanism results in the separation of elementary particles of abrasive material from the grain surface. There are no clear explanations of this wear mechanism in the research literature. This paper tried to interpret the mechanical wear of the abrasive grain from the standpoint of kinetic theory of solid strength based on the thermofluctuational mechanism of material destruction. The suggested technique of simulations of contact interaction between the abrasive grain and treated material allows one to calculate a size of the worn part of an abrasive grain due to the mechanical wear.
