电火花线切割加工工艺参数优化研究

在对国内外电火花线切割加工的研究现状及发展趋势综述基础上，针对加工工艺参数优化采用理论分析的方法进行研究。分别通过传统的统计分析法和人工神经网络对线切割加工工艺参数进行优化。统计分析法采用正交矩阵法建立了工艺指标与影响因素之间的关系模型．通过约束优化法进行参数优化：采用误差反向传递神经网络的智能方法通过时实验数据的学习来对工艺参数进行优化，结果表明神经网络方法优于传统方法。为进一步实用化奠定了基础。

Study of the Parameters Optimization in WEDM

On the basis of generally stating present study status and the developing tendency of WEDM in the world, parameters optimization of manufacture process is studied by theoretical analysis method, and the manufacture process parameters of WEDM are optimized by traditional statistics analysis method and artificial NN separately. Statistics analysis method uses orthogonal matrix method to set up the relation model between process parameters and affecting factors, the parameters are optimized by constraint optimization method. Whilst, the process parameters is optimized by studying the experimental data using the intelligent method of error reverse transform NN, and the results show that NN method is better than traditional one, this provides a base to real practice.
