By means of high speed gas stream compound with coaxial cutting gas for pulsed Nd:YAG laser on cutting of ceramics,the technological parameters affected on the thickness of re-cast layer and the exiting of crack in re-cast layer were studied.As well as a practically composite method to obtain a minimum thickness of re-cast layer on cutting of Al2O3 Ceramics was developed.
