| Abstract: | The working process of point grinding on curve surface was presented. CCD online monitoring system was developed, the images of grinding area can be gathered in real time by using CCD camera. A location algorithm of subpixel edge is studied. The outline edge of grinding wheel can be extracted with the algorithm, and the detected result is compared with the perfect outline. We can see from the experimental result that the method of by using monitoring grinding by using is valid. Detection precision and results are reasonable. |
