Abstract：

Simulated annealing was led into genetic algorithm to reduce the genetic algorithm of operating time and improve its efficiency.At the same time,the initial value was dealed with using chaos optimization in order to achieve global optimization.Punish Function Method was used as the treatment tool for the binding conditions of the objective function to expand the scope of application of genetic algorithms.And combining laser bending of sheet material examples,comparison with genetic algorithm and ANN was carried out detailedly.Results show that the process variables obtained by Integrated Genetic Algorithm is better than that of single algorithm.
