Cutting depth model of abrasive water jet was established based on the experimental data of abrasive water jet cutting concrete by applying artificial BP neural network and MATLAB neural network tool box.The model includes several jet parameters: jet pressure,standoff distance,diameter of abrasive,mass flow rate of abrasive,diameter of abrasive nozzle,length of abrasive nozzle and traversing velocity of jet.The result of comparison between the model-predicted data and experimental data shows that the model ...
