Beschreibung
Zusammenfassung:	A number of future signals are calculated during a succession of time intervals, not all the digital signals being calculated at the same time. In each interval, a tool position signal is delivered, which is of a constant amplitude corresp. to the required tool position. This signal is fed to a signal processor where it is converted into a continous signal which changes progressively so that its amplitude is related to the successive values of the tool position signals. The continuous signals is fed to a closedloop control system which controls the movement of the tool holder. The control system has proportional and differential feedback.
