In this paper, a critical study into the dynamic form of abrasive particles through polishing are made, which are under “inconsistent curvature contact” status. In this system, some abrasive particles are colored up and mixed with ordinary ones, by utilizing transparent working surface and stroboscopic light as well; motion state of abrasive particles can be photographed by high speed shot technology. This method can get serials of images while polishing. By using digital image processing technology, distribution of abrasive particle field can be obtained finally. In this paper, the abrasive particles field is researched to obtain the perfect abrasive particle field after purposefully control. Then the influence of the removed material caused by abrasive particles field can be improved, so it can provide strong theory foundation and practice guidance to surface polishing practice.
