Abstract
This research deals with the high precision flat surface finishing method by automatic scraping machine. By Whitworth method, high-precision surface plates were finished without using a reference surface automatically, and it was certainly the work process from the pattern scraping (rough scraping) up to fine scraping. Scraper direction was changed every time to make scraping pattern on the surface. The method of dividing some image matrix that is one of image processing technique was able to take high precious image. Finally, surface flatness and scraped marks per square inch was measured to estimate the scraping performance of automatic scraping machine.
