Tatsuo Asami, Toshimi Oohata, Kimio Wada, Kazuhiro Takahashi

Processing for joining glasses frames and glasses lens is mainly done by a diamond grinder by grinding down material for each lens to match it with the frame. In this case all the ground-off material is handled as industrial waste and is useless. In addition, the dusty and smelly inferior processing environment and troublesome processing methods become a problem. A technique to solve these problems by automatic processing with a machine is suggested in this report. First, image data is acquired by image processing from a USB camera, and the solution technique extracts the image of a part to be cut. Next, the coordinates of a cut part are calculated from an extracted image, and a message is transmitted to a motor system order controller. Lastly, the product of a joint development company which is a processing machine that drives a diamond cutter machine and motors is an automatic cutting system. As a result of implementing these systems, and having examined them, it was shown that they had sufficient performance.
