Abstract

The characteristic of abrasive particles field is important to polishing process. 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, abrasive particles are mixed with colored ones, by utilizing transparent workpiece and stroboscopic light as well; motion state of abrasive particles can be photographed by high speed shot technology. This method can get the transient state during polishing and serials of images which are clear enough to this study. By analyzing the results, distribution of abrasive particle field can be easily proved. The images we get through using this technology, in addition to the normal noises resulting in inputting, collecting and processing approaches, commonly, there are noises from the transparent workpiece itself. Then, the most appropriate processing method will be chosen according to the source of noises. Consequently, colored abrasive particles will be abstracted as the characteristic points. In that case, a fit line of the trajectory of colored abrasive particles' motion can be obtained finally.
