LMBP neural network has stable performance and rapid convergence, which can be applied to the cutting surface quality prediction. The user interface was designed in MATLAB software, which could be used to read process test data from files and set the input and output of the neural network; the neural network program based on LMBP algorithm was developed, and the full software was compiled and verified. The software was used in the cutting surface quality prediction. The prediction error is smaller with the experimental results, the prediction results have high precision; the software is simple, suitable for the field staffs.
