Beschreibung

For an active compensation of workpiece clamping failures in lathes a novel fine positioning method using an active chuck is developed. The position of the workpiece is determined by two tactile displacement sensors. The chuck consists of integrated stepper motors which compensate eccentric displacement and tilting errors. The corrected position is fixed by frictional locking caused by the tensile force. All components required for this purpose are implemented in a lathe and examined in a turning process. The results proof a significant reduction of eccentric errors and the basic suitability of this method.
