7.2.4 Dynamic feedforward control
☑ Basic configuration
Inaccuracies in the resulting workpiece contour due to following errors can practically be
eliminated using dynamic feedforward control FFWON. The result is excellent machining
precision even at high tool path feedrates. This is clarified with a circularity test on the
machine.
