As an important application of Laser Rapid Forming

laser bending technology of brittle materials has broad prospects. In this paper

experiments on bending of Al2O3 ceramic slice with CO2 CW-laser are carried out at various laser processing parameters

including laser power and scanning velocity. Laser linear energy density is introduced to discuss the best processing parameters

and bending characteristics are briefly analyzed according to the high temperature properties of Al2O3 ceramic. Experimental results show that the Al2O3 ceramic slice is bent by CO2 CW-laser

and the bending angle reaches up to 2° . Laser bending processing of Al2O3 ceramic slice is strongly sensitive to temperature. There exists a critical temperature

above which

the bending angle increases greatly. The best rang of laser linear energy density for bending Al2O3 ceramic is 17～24 J/mm.
