Study on Borosilicate Glass Sheet Reverse Bending with CO_2 Laser

Wu Dongjiang Niu Fangyong Zhang Qiang Guo Dongming Key Laboratory for Precision and Non-traditional Machining Technology of the Ministry of Education,Dalian University of Technology,Dalian,Liaoning,116024  
Experiments of borosilicate glass sheet reverse bending by CO2 CW-laser were successfully presented,and suitable processing parameters of reverse bending were given for specimen with thickness of 150μm.The influences of scanning number and specimen width on bending results were investigated,and then experimental phenomenon was analyzed by comparing with the forward bending.In view of the suitable processing parameters and experimental results,the buckling mechanism can be sited as the laser forming mechanism responsible for reverse bending of glass sheet.The reverse bending progress increases the flexibility of laser forming and provides a new way in machining for intricate parts.
