    摘要:

    运用正交试验对2A12铝合金激光切割参数中激光功率、切割速度、气体压力的工艺数据进行极差、方差分析,得到综合质量最优的因素组合。并以切口粗糙度为研究对象,建立其BP 神经网络预测模型,训练后的模型在验证样本测试中的预测值和实际值之间误差较小,从而证明了建立BP 神经网络来预测激光切割切口表面粗糙度的可行性,在实际生产中对指导激光切割获得较好的切割质量有一定的实用价值。

    Abstract:

    2AL2 Aluminum Alloy cutting experiment was carried on CO2 laser cutting machine.The process data of laser power,cutting speed and gas pressure were analyzed by means of range and variance analysis of orthogonal test,and the optimum technological conditions for the best quality were determined.Taking the incision roughness as the object of study,by building a BP neural network prediction model,the error between the actual value and prediction was small,which proved that BP neural network was feasible to predict the laser cutting surface roughness.It has certain practical value in the actual production to obtain good cutting quality in laser cutting.
