数控机床的位置控制一般都设计成一阶无静差的调节系统，即各伺服轴在静止时轴的位置被定位在目标位置，误差为零。在进行轮廓插补时系统出现跟随误差。跟随误差的大小与系统的增益系数有关，它们之间的关系可用下式描述：ε＝１ＫｖＶ式中ε——跟随误差Ｋｖ——增益系数... CNC machine tool position control are generally designed as a first-order no-error adjustment system, that is, when the servo axis in the stationary axis position is located at the target position, the error is zero. The system appears to follow the error when performing contour interpolation. The magnitude of the following error is related to the gain coefficient of the system. The relationship between them can be described by the following equation: ε = 1KvV where ε - following error Kv - gain coefficient ...
