此外，还针对Y轴方向上的由于刀架位置变化导致的X轴方向上的不同步进行了负载动态补偿。
In addition, for the X-drift asynchronous problem caused by Y-drift tool position variation, load dynamic compensation is proceeded.
为了实现速度同步，通过检测不同步时横梁上的交叉耦合应力变化，对不对称负载进行动态补偿。
In order to realize speed synchronization, asymmetry loads are compensated dynamically by measuring the variety of cross couple stress of the crossbeam when gantries are not aligned.
但由于负载经常处于变化之中，采用固定容量补偿方式常常不能满足要求。
However, it can't adjust flexibly compensation capacity due to load in variable state frequently.
