Abstract

The invention relates to a method and a device for guiding the movement of a moving machine element on a numerically controlled machine, whereby maximum possible track speed, maximum possible track acceleration, and maximum possible track jerk are defined by means of given restrictions on track axes. The local minima for the maximum possible track speed are determined, whereby for each local minimum a corresponding left-sided and right-sided track speed segment is determined, whereby, for track values for the displacement track to the left and right of a given minimum, the resulting track speed is determined by using the maximum possible track jerk and the maximum possible track acceleration until the track speed exceeds the maximum possible track speed to the left and right of the minimum, a track jerk curve for the movement guidance is hence determined. According to the invention, a simple method and a simple device for movement guidance of a moving machine element on a numerically controlled machine are achieved, with as good as possible a usage of the restrictions on machine axes of the machine.
