| Abstract: | As the common exit for both the gas and focused beam, the nozzle is one of the critical components in gas-assisted laser cutting. The goodness of a nozzle design will directly influence the cutting quality. Theory and experiments show that the surface irregularity can be improved with appropriate control of the fluid dynamic characteristics of the nozzle. To guarantee a high cutting quality, the nozzle should meet the requirements on the mechanical stability in operation, on adjustability of laser beam and gas tightness. The nozzle aperture and clearance are also among the most important parameters. Test results show that a height sensing system is needed in order to guarantee a proper nozzle clearance during cutting. |
