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.

The application discloses a kind of air cushion furnace process section tension control equipment, including tensioning machine roller group, detection mechanism and furnace front carrier roller, and tensioning machine roller group and furnace front carrier roller are cooperated with strip winding;Further including the control system being respectively communicated with tensioning machine roller group and detection mechanism, control system can control the rotating speed of tensioning machine roller group according to the tensioning degree parameter of strip fed back by detection mechanism;Detection mechanism includes first detection device and second detection device, if the thickness of strip is less than set thickness, then the tensioning degree parameter of strip is detected by first detection device;If the thickness of strip is greater than set thickness, then the tensioning degree parameter of strip is detected by second detection device.The air cushion furnace process section tension control equipment is higher in control precision to the tension of strip, can satisfy the tension control demand under the working condition of smaller tension.The application further discloses an air cushion furnace process section tension control method applied to the air cushion furnace process section tension control equipment.
