厚板ガラス用切断機の開発

抄録

This report presents the development of a cutting machine for thick plate glass with "Elastic Working" which makes use of the progress of natural crack occurring at the fracture of brittle materials. The characteristics of this machine are as follows : ( 1 ) The system of the cutting machine is simple and plate glass can be cut to the thickness of 22mm along the desired scribe line without generating waste, noise, dust or heat, irrespective of the length. ( 2 ) The cut section is mirrorlike, and it is perpendicular to the face of the plate glass. ( 3 ) The energy required for cutting the plate glass is very small, and the cutting time is very short.
