Study on cylindrical lapping for the structured fish scale surface
In order to lapping the structured fish scale surface with traveling wave structure on the surface of the cylindrical work-piece,firstly,based on the characteristic analysis of the surface morphology of fish scales in nature,the mathematical model of the structured fish scale surface of cylindrical workpieces arranged along axial direction was established.Secondly,according to the principle of lapping and topological theory,a structured topological whetstone for lapping fish scales on cylindrical surfaces was designed.Then,according to the abrasive grain movement trajectory for the cylindrical lapping,the boundary conditions for reali-zing the lapping processing of structured fish scale surface on the cylindrical workpiece were discussed.And the cylindrical lap-ping process was simulated to obtain the structured fish scale surfaces with traveling wave structure.The results show that cylin-drical lapping for the structured fish scale surface can be realized by using the designed structured topological whetstone;by changing the amplitude and frequency of lapping,the shape parameters of the structured fish scale surface also change,but its sur-face topological properties do not change.
