Specimens of pure aluminum, copper, and iron were abraded on silicon carbide abrasive papers. The sliding velocity was varied between 0.5 and 82 mm/s and a range of abrasive grit sizes was used. The cutting force is composed of a friction contribution, which accounts for 70–90 percent of the total, and a plastic work contribution. The plastic work contains a velocity-independent and a velocity-dependent contribution. The velocity-independent part is the work to deform the metal plastically to a true strain of approximately 5. The velocity-dependent part is relatively small and is proportional to the logarithm of the velocity. It is caused by the effect of strain rate on the flow stress. No effects of grit size alone on strain rate were found.
