Metal manufacturing technology is a process contains multiscale coupling phenomenon where fracture of atomic bond in the microscopic area will lead to the material removal in the macroscopic area.

In order to realize dressing of fine diamond grinding wheel effectively, removal behavior of metal bond for dry and wet coolants is investigated.

An increase in the specific surface area of the alumina pellets enhances the HCHO removal, and this indicates that the adsorbed HCHO species may have a lower C-H bond breakage energy.
