1417 熱応力を利用した脆性材料の新しい高速割断技術に関する研究(G04-2 機械材料・材料加工(2),21世紀地球環境革命の機械工学:人・マイクロナノ・エネルギー・環境)
詳細
The scribing process has been performed until now using an edge for high-speed cutting of glass. However, in recent year, the scribing process which guides a crack only to the surface is beginning to spread using the thermal stress generated by laser heating. When this method is compared with the conventional method, it is advantageous that a cross section of glass is beautiful and that the yield rate is high. By this research, it proposes about different new heating point form from conventional laser scribing using CO_2 laser, and the possibility of the scribe processing is described.
