In order to judge the laser cleaning effect,optimize the laser cleaning process parameters,evaluating the laser cleaning effect is important.Laser cleaning experiment was carried out with 1 000 W laser cleaning machine.Combining experimental data,machine vision technology and surface performance testing technology were used to evaluate the effect of laser cleaning from both macro and micro aspects.Three evaluation indexes of cleanliness,roughness and cleaning efficiency were proposed.According to the evaluation index,the laser cleaning effect evaluation criterion “Lcq” was formulated.Based on this system,an intelligent evaluation system for laser cleaning effect was developed.The test results show that the laser cleaning effect rating evaluation system is objective and accurate,the system operation is stable,and the on-site operation of the laser cleaning equipment can be guided,so as to adjust the parameters of the laser cleaning machine faster and improve the cleaning effect.
