8.2 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.
