With the atomistic model, the nano-grinding process could be performed between a silicon workpiece and diamond tool under different grinding speed. To reach a thinnest SSD layer, nano-grinding speed will be optimized in the range of 50-400 m/s. Mechanical properties of six damaged silicon workpieces with different depths of cut will be studied.In the process of nano-grinding, the grinding speed and depth are the key factors that affect the removal rate. The variation of these parameters will inevitably affect the crystal structure and subsurface defects, and then impact the quality of the subsurface layer. Therefore, in order to explore the specific impact of grinding speed and depth ...
