• This study aims to reduce the work-affected layer of machined surface by carrying out the machining at the speed beyond static propagation speed of ductile materials. This paper reports on the result obtained through the molecular dynamics simulations on such machining process. In the simulations, the workpiece and the tool are assumed to consist of monocrystalline aluminum adn rigid diamond, respectively. From the ultra high-speed grinding 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. The effective speed to the reduction of plastic flow is also clarified.
