Estimation of Material Removal in Usm Process — A Theoretical and Experimental Study

On the mechanism and mechanics of material removal in ultrasonic machining

“…They assumed that each abrasive grit removes a hemispherical portion from the workpiece due to material fracture caused by indentation. Based on these models, Saha et al [9] suggested that it is the tensile stress that causes the workpiece fractures. However, the phenomenon of tensile stress generation by grits is not discussed.…”

“…(8)(9)(10). Now the actual depth of indentation of abrasive grain in the workpiece after incorporating the contact deflection can be expressed as…”
