This invention discloses a method for CO2 continuous
laser cutting of CFRP material. The method employs a CO2 continuous
laser engraving and
cutting system to
cut CFRP material. After adjusting the corresponding working parameters, a portion of the CFRP material to be
cut is taken as a sample, and a rectangle is obtained through trial
cutting. The diameters of the pits generated by the spot
laser are measured horizontally and vertically twice, and the
average diameter is calculated. Simultaneously, the continuous
laser power density is calculated, and the
height difference between the four corners and the center of the rectangle is measured to obtain the surface fluctuation value (Fv). Different scanning speeds, number of consecutive
processing cycles, and Z-axis scale values are selected, and trial cutting is repeated on the sample. When the measured Fv is at its minimum value, the
thermal damage to the material is minimized. The scanning speed, number of consecutive
processing cycles, and Z-axis scale value at this minimum value are used as the working parameters for cutting the CFRP material. This invention effectively controls the
thermal damage to the CFRP material during
processing and improves the processing effect of laser-processed CFRP material.
