摘要
约束适应控制系统用于径向非等刚度回转零件的磨削过程中,并不能提高被磨表面的几何精度。其原因在于,该系统产生的补偿力不符合工件的成圆机理。针对这一问题,本文设计了一个自适应控制系统用于磨削过程中,使补偿力与成圆机理相符。
The paper analyzes the reason why the adaptive control constraint system can not be used in grinding process for some shafts,whose rigidity is varying in the radial directions. It also introduces a self - adaptive control system which is applied to the grinding process in order to solve this problem and improve geometric accuracy of these shafts.
