Abstract: This study aims to reduce the work-affected layer of the machined surface by carrying out the grinding at the speed over static propagation speed of plastic wave of ductile materials and also aims to clarify such super high-speed machining mechanism. This paper reports on the result obtained through the molecular dynamics simulations and experiments on the super-speed grinding below and beyond static propagation speed of aluminum. From the simulation results, it is verified that the plastic deformation is reduced when the machining speed exceeds the material static propagation speed of plastic wave and its mechanism is completely different from that of the ordinary grinding process. Experimental results also show the improvement of the surface integrity when the machining speed exceeds the material static propagation speed of plastic wave. [Copyright &y& Elsevier]
