Genauigkeit koordinierter Bahnbewegungen

Precision of coordinated path movements. Apart from motions which a machine element describes only translationally or rotationally, mainly those movements are of interest for mechanical engineering, specifically for handling and robot technology, which occur by an overlaying of elementary forms of movement. The time-related and geometrical deviations of actual from ideal movements along a path call for a systematic description. This article provides an overview of definitions of movement deviations and of the state of standardization.
