Automatic Measurement of 3-Dimensional Profile of Free-Formed Surfaces by Using Touch-Trigger Probes

접촉감지프로브를 이용한 자유곡면의 삼차원형상 자동측정

This report presents an automatic measurement method of 3-dimensional profiles of free-formed surfaces, by using a touch a touch-trigger contact probe along with a conventional coordinate measuring machine. The method proceeds in three steps; The surface profile under consideration is traced by the probe in an automatic manner, and then its measured data is compensated by considering the actual probe radius. Finally the compensated data is rearranged in the form suitable for the further processings of CAD/CAM applications. Some experimental results are discussed to verify the validity of the method suggested in this study.
