Zero Width Glass Cutting with CO 2 Laser
Laser cutting of glass in not a novel technique, excellent results have already been achieved by various research institutes. There are several patents concerned with controlled cutting of glass with zero width and other brittle materials in a straight line using CO2 laser beam. Laser beam glass cutting produces a high quality cut edge with minimal microcracking. This is achieved using a controlled cleaving of glass through a combination of heating and cooling. Laser separation of glass with zero width can be summarised by the following steps:
Laser separation of flat glass in electronic-, optic-, display-, and bio-industry (Invited Paper)
Up until now, conventional cutting methods by using metal or diamond wheels have been widely in use in numerous glass industries. Along with the market trend towards clean and more sophisticated process, constraints by the traditional methods have been unavoidable. Hence, laser separation is seen as an alternative and breakthrough solution to many and in this paper, an overview on laser separation as a whole is provided in terms of its process theories and its system as process equipment. Also glass application varieties as well as market requirements are discussed.
Post-Processing by Laser Cutting
There are two methods for brittle cutting of glass sheets, namely the full-body and the microcrack cutting. We will describe the relevant processes, how to model them, and how to find advantageous process data via simulation.
