Abstract

Based on the basic theory of artificial neural network,BP network model is founded to predict the highest surface temperature and bending angle in the process of laser sheet metal bending.Experimental result and numerical simulation result verified by experiment are used to train BP network by means of MATLAB software.Sample data regularity of nonlinear is curve fitting through BP network so as to optimize technological parameters and provide effective foundation for actual production.
- artificial neural network,
- laser sheetmetal bending,
- surface maximum temperature,
- bending angle
