Abstract
A circle cutting method for plate glass is proposed. Using this method, plate glass can be cut into many small circle plates almost simultaneously, irrespective of the number of plate glass desired cut. This method is called “Elastic Working” which aggressively exploits the progress of natural cracks occurring at the fracture of brittle materials. The characteristics of this method are as follows. (1) The plate glass can be cut almost without generating noise, waste or dust. (2) The cut section is perpendicular to the face of the plate glass. (3) The energy required to cut is minimal and the cutting time is very short. (4) The ceramic plate can also be cut as well as the plate glass.
