摘要
利用CO2连续激光对厚度为150μm的硼硅酸盐玻璃薄片进行了反向弯曲试验,得到了适合反向弯曲的激光加工工艺参数。研究了激光扫描次数及玻璃样品宽度对反向弯曲效果的影响,并就相关试验现象结合正向弯曲成形进行了比较分析。综合考虑实现反向弯曲成形的工艺参数及试验结果,初步确定激光加工玻璃薄片实现反向弯曲的机理为翘曲机理。反向弯曲技术进一步增加了激光弯曲成形的柔性化,为复杂零件的加工提供了新的解决途径。
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
