Example Embodiment
[0023] Example one
[0024] Such as Figure 1-5 As shown, a method for controlling the parameters of laser peening to monitor the surface roughness of a blade includes the following steps:
[0025] Step 1: Use the surface roughness measuring instrument (10) to measure the surface roughness of the variable cross-section thin-walled complex blade (5) before the laser shot peening through the transmission mirror (4) to obtain the measured value before the treatment. The measured value before processing is transmitted to the computer control system (1) through the information acquisition system (11);
[0026] Step 2: Computer control system (1) According to the required surface roughness accuracy requirements of the variable cross-section thin-walled complex blade (5), the flat top variation and roughness of the laser peening beam built in the computer control system (1) In the database of the correspondence relationship between the linear interpolation methods, determine the laser pee...
