This work presents a method for automating the glass cutting process in a product line of a touch screen panel. The mechanical roller cutting method has been used for some time for industrial processes of glass. However, the existing mechanical glass cutting method needs workers to break the glass after the scribing process. The glass can become damaged during the breaking process because it is difficult for a human to apply the same pressure and direction every time when breaking the glass. If we automate these processes, we can apply consistent pressure and breaking angle. As a result, we can obtain an improved production yield rate. In addition, the breaking process can be dangerous for worker operating the machinery. Glass micro powders scatter during the scribing and breaking process. When workers handle the glass, they are exposed to this danger. Therefore, an automatic glass cutting machine needs to be developed in order to eliminate workers from these processes.
