Research on the mapping grinding of dimple surface with ordered pattern based on topological theory

Since the structured dimple surface is one of important functional drag-reducing surfaces, research on its efficient fabrication technology great significance for practical application this surface. Therefore, in order to grind surface, a topological mapping grinding method was proposed based kinematics principle and point set topology. Firstly, spaces workpiece wheel were established, features extracted analysis topography with ordered pattern. Then, topology equation process constructed generating mechanism about geometry, designed according equation. Finally, geometry simulation, influence parameters studied, experiment carried out. The results show that can achieve ground feature be changed change parameters, but attributes remain unchanged under condition satisfying proper speed ratio.
