Predicting the Intensity of Physicochemical Interaction between the Abrasive and Workpiece Material Depending on the Chemical Composition of the Material Machined

Physicochemical mechanism is one of the wear mechanisms of the abrasive grain in grinding. Existing scientific researches which deal with the wear of the abrasive grain show the presence of this wear mechanism but do not characterize it from the quantitative point of view. The article contains the results of the empirical studies on the physicochemical interaction between the abrasive grain and the workpiece material while grinding. The empirical studies allowed to determine the quantitative characteristics of physicochemical processes in grinding. The developed empirical models can predict the coefficient of chemical affinity for the workpiece materials with a variety of chemical compositions. The mathematical method used in this research makes it possible to define the size of the abrasive grain portion is worn as a result of such physicochemical interaction. In future, this circumstance will predict the extent of the abrasive tool wear under different technological conditions in order to define its operating capacity and apply the tool efficiently in multipart manufacturing.
