摘要
PURPOSE: A method and a device for cutting a non-metallic panel, such as a glass panel by laser beam is provided to obtain uniform and high-quality cut section from the starting point to the end point and to completely separate the cut parts. CONSTITUTION: The method for cutting a non-metallic panel comprises the steps of: forming an initial crack at a starting point to be cut in a desired direction, conveying a cutter along a predetermined cut line at a conveying speed coincided with a first constant velocity zone of a predetermined speed curve, and performing scribing and breaking by using laser beam synchronized with the conveying speed; conveying the cutter along a predetermined line at a conveying speed coincided with an acceleration zone of a predetermined speed curve, and performing scribing and breaking by using laser beam synchronized with the conveying speed and having gradually increasing output; and conveying the cutter along a predetermined line at a conveying speed coincided with a second constant velocity zone having a speed higher than that of the first zone, and performing scribing and breaking by using high-output laser beam synchronized with the conveying speed.
