Description

This paper deals with an automatic scraping machine with image recognition system for bearings of surface plate. The automatic scraping machine consists of a large size XYZ stage for machining, a scraper and a CCD camera. The scraper attached on the large size stage just like skilled worker. After manually painting the bearings with red rouge, the image processing system with a colored CCD camera recognizes the bearings from the surface image. By image measurement including the calibration method, black bearings position detecting and tool positioning became possible high-precisely. The scraping level was decided by the area of measured black bearings, and as a result, efficiency improvement of the scraper work and reduction in the scraping error were attempted. For the surface plate finish, the process of automatic scraper work from the pattern scraper work to the recognition scraper work was examined. The positioning accuracy of the scraper using image recognition was 0.3mm. As a result, the surface flatness of the surface plane finished by this scraping machine was 11.6μm which is the same precision of general slide surface.
