Abstract

To avoid variation between the resultant paths of multiaxis motions of a machine element for different override curves, distance-time curves of the axis motions are stored for an override value of 100%, and a relevant distance-time curve is subjected, in synchronism with a time sequence of selectively varied override values for each axis, to a time expansion which is inversely proportional to the respective override value.
