Study on Designing and Grinding the Revolution Body Surface with Phyllotactic Dimple Pattern
In order to grind the structured dimple surface of the phyllotactic pattern on the revolution body surface,the revolution body surface was divided into the structured element based on the theory of phyllotactic pattern,and then a 3D model of dimple surface with phyllotactic pattern on the revolution body was designed to analyze the topological variation of the dimple surface of the structured element,and the strategy for grinding dimple surface with spherical mounted point was given.Finally,the influence law of different angle of the spindle and phyllotactic pattern coefficient on structured surface was obtained through computer simulation,and preliminary grind-ing experiment was conducted.The results show that the grinding method can achieve the fabrication of revolution body surfaces with phyllotactic pattern of dimples.As the coefficient of phyllotactic pattern decreases,the distribution of dimples on the revolution body sur-face becomes sparser.When the spherical mounted point rotates around different axes for grinding,cross texture,vertical texture and con-centric circle texture can be formed inside a dimple.
