Abstract
There is disclosed a method of cutting a plate glass mother material in which a plurality of grooves are scribed/processed beforehand on one main surface, and appropriate pressing is constantly performed, so that more preferable materials to be pressed can be formed. When a plate glass mother material is pressurized by an indenter and cut in a portion of groove D vibration is momentarily generated. The vibration is transmitted to a vibration sensor via an indenter base Subsequently, at the time when the vibration sensor detects the vibration, a Z-axis servo motor of a pressing device stops, and pressing by the indenter stops. Therefore, the indenter does not advance by more strokes than necessary, glass in a cut portion can be prevented from being chipped.
