Abstract
Scraping is a fundamental technique for the production of precision machine tools. The accuracy of machined components is lower than the accuracy of machine used to make the components. The scraping techniques were used to improve component surface flatness or to develop proper oil pockets for slider and thus the machine tool accuracy and performance can be improved. However, scraping is a time consuming process. The purpose of this study is to develop an auto-scraping system which can be used to identify the tinted area and scrape the tinted area. Basically, the developed system includes a machine vision system and a mechanism with tri-axial movement for scraping. With this system, the image of the work surface captured by the vision system was processed and analyzed to identify areas by specific color space. The scraping mechanism is then directed to the desired area for scraping automatically.
