    • Abstract
  • In order to solve the crack caused by thermal stress during the process of laser cutting for the toughened glass, the FLUENT software was adopted to analysis the water presure and the stability of water beam based on water & laser coupling model, and the optimised parameters were obtained. Then experiment based on the optimised parameters was conducted to verify the anslysis results. The results show that, incision surfaces of both No.1 and No.2 samples are smooth and slot with the width of 100μm under the condition of nozzle diameter 0.4mm, water pressure 20MPa, laser power 48W and cutting speed 20mm/s. Thedesign of coupling device with two water filling nozzles is applicable in the whole process of laser cutting for the toughened glass.
