摘要
数控进给系统在起始和停止阶段 ,应避免产生冲击、失步、超程和振荡 ,以保证运动部件平稳准确定位。提出了加减速控制采用指数规律控制方法 ,基于指数规律获得数学模型 。
NC feed system abstains shock,miss step,overstep and surge on start and stop stage.And so motion part is ensured orientation of placidity and nicety.The paper bring forwards method of accelerating and decelerating control of adopting index rule.Feed control is arrived at characteristic of optimal control based on mathematics model of index rule.
