The effect of the cutting parameters on the surface roughness in a turning operation has been investigated using response surface methodology. The mathematical prediction models for surface roughness have been obtained for a common mild steel. The equation is used for determining the optimal cutting ...
1, is also called kinematic or theoretical surface roughness and is given approximately by the following equation [1]:Rth≅f28rn,where f is the feed and rn is the tool nose radius. The kinematic surface roughness is widely used to estimate the surface roughness in the turning process, but...

For sediment transport calculations, the shear stress related to skin friction is used to exclude form roughness from bedforms and channel walls, where (5)with the Keulegan equation to estimate the skin friction-related Chézy number (C′) (m1/2/s): (6)where D90= 90th percentile of ...
When calculating the surface normals by analytical methods, additional precomputation for each specific surface equation is necessary. This is avoided by representing the nominal surface by a point cloud as described in Sect. 1. The point cloud represents a flexible basis for the overall tool path...
