智能控制型径向切入磨削加工系统

针对径向切入式磨削加工过程 (尤其是薄壁工件 ) ,提出了一套新的磨削工艺程式及与之相适应的递阶式智能控制模式。其上层是一个基于知识并具有学习能力的智能决策系统 ,它根据加工要求 ,按照当前加工条件 ,自动规划加工参数 ;下层的自适应环节能实现对磨削过程的在线监测和实时控制。仿真与试验结果表明 ,该方法能较好地应用于实际磨削过程 ,可在更短的时间内获得更理想的加工效果。这一系统具备了相当的柔性 ,可以适应小批量多品种的加工要求。

To the radial\|feed grinding process,a new process program has been presented.Based on the analysis of the grinding mechanism,the layered intelligent control strategy is put out,which treat the final actual size of the workpiece as the optimization aim.The simulations and experiments have shown that this method can be used primely in the on\|line control of the grinding size precision.The more accurate grinding result can be obtained within shorter time,which can be seen especially in the grinding process of the thin thickness workpiece.\;[
