Deformation mechanism and force modelling of the grinding ...

When the abrasive grinding depth is greater than 24 nm, brittle-ductile coexisting surfaces are generated, where surface and subsurface cracks are initiated at the intersections of slip lines, followed by further propagation and the plastic deformation is accompanied with the formation of nanocrystals and nanovoids, as shown in Fig. 6(b).

A Surface Generation Mechanism of Grinding - Scientific.Net

This paper presents a surface generation mechanism of grinding that captures the microscopic interaction between the abrasive grains and work-surface. The mechanism utilizes both deterministic and stochastic formulations and deals with such realistic constraints as loss/wear and uneven distribution of abrasive grains, roughness of already-ground work-surface, and machine stiffness.
