In this paper, a model that predicts the effects of roughness, asymmetry, and flatness on the adhesion, contact, and friction forces in MEMS interfaces is presented. The three key parameters used to characterize the roughness the asymmetry and the flatness of a surf...
The workable diameter is 630mm or less; however for the workpiece having higher requirements on surface flatness and roughness, the surface flatness of 0.003mm and the surface roughness of 0.8µm (Ra value) can be achieved. The simple and concise dialogue operation and...

The results suggest that Townsends similarity hypothesis for 2D surface roughness is relatively well approximated in the outer region of the flow as reflected by the collapse of the distributions of velocity defect, turbulence intensity, skewness, and flatness when scaled with δ....
