Abstract: Device and method for positioning a precision part on a turntable (130). The device (100) comprises at least two distance sensors (121.1, 121.2, 121.3), which operate in a contactless manner and are situated in a previously known configuration to a rotational axis (A1) of the turntable (130). The measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) are radially oriented in the direction of the rotational axis (A1) so that the measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) meet in a virtual measuring point (MV). The distance sensors (121.1, 121.2, 121.3) are connected to analysis electronics (200). Output signals (a.1, a.2, a.3) of the distance sensors (121.1, 121.2, 121.3) may be processed on the basis of the analysis electronics (200), in order to allow coaxial centering of the precision part (11) in relation to the rotational axis (A1) upon placement of the precision part (11) on the turntable (130).

Abstract: A device for measuring a rotationally symmetric precision part, having a dog, drivable via a drive, and a revolving centering means, the dog and the revolving centering means being positioned in such a way that a rotationally symmetric precision part to be measured may be non-positively clamped coaxially between dog and centering means. A first angle measuring system is assigned to the dog, which provides signals that permit the drive-side angular position of the dog to be stated, and a further angle measuring system is assigned to the revolving centering means, which provides signals that permit the output-side angular position of the centering means to be stated. Software means are provided which determine slip between the dog and the rotationally symmetric precision part through a comparative calculation on the basis of the drive-side angular position and the output-side angular position.
