摘要
为了提高多轴联动CNC机床的加工精度,减小由机械传动及电气控制等因素造成的轮廓误差,针对多轴联动CNC机床伺服采用交叉耦合参数选择困难及稳定不强等问题,提出一种交叉耦合轮廓补偿的控制方法,建立交叉耦合轮廓误差补偿的模型,搭建了x轴、y轴及z轴仿真实验平台。仿真实验结果表明:轮廓误差补偿的算法使用交叉耦合误差补偿算法进行控制,可以大大降低轮廓误差。
In order to improve the machining precision of multi axis CNC machine tool,decrease contour error by mechanical transmission and electric control factors,aiming at the difficulties and instability of cross-coupled parameter selection in multi axis CNC machine tool servo,a kind of cross coupled contour error compensation control method was put forward,cross coupled contour error compensating model was established,and the x axis and y axis and z axis simulation experiment platform was set up.Simulation results show that the contour error compensation algorithm is controlled by cross coupled error compensation algorithm,which can greatly reduce the contour error.
