An arrangement including a machine tool with a chuck, a measuring device, a robot arm as well as a control device. The chuck is rotatable about a chuck axis. The robot arm carries at its free end a gripping device for reception of a workpiece. The measuring device has two sensor units. The measuring device has two sensor units. By means of the control device an automatic adjustment method can be carried out. First the robot arm is controlled for gripping a workpiece and subsequently the workpiece is positioned in the range of the measurement locations of the sensor units depending on measurement signals such that the deviation in the inclination and the offset between the workpiece axis and the chuck axis is within a predefined tolerance range. This procedure is at least carried out in two different rotation positions and is iteratively repeated if necessary.
