In order to improve the precision of the laser cutting, aiming at the defects of traditional neural network parameters optimization, an improved laser cutting notch size Predictive model. Firstly, the laser cutting incision size and process condition data were collected and normalized. Then the training samples were used to train the neural network. The quantum particle swarm optimization algorithm was used to solve the traditional neural network parameter optimization problem. The laser cutting incision size Prediction model, and finally use the test sample to verify the prediction model. The results show that the model can well fit the relationship between the process conditions and the size of the incision, which can effectively predict the incision size and provide a theoretical basis for improving the quality of laser cutting.
