Abstract
A device is provided for measuring roundness of a mechanical object even if the mechanical object performs an orbit movement. The orbital movement and the surface roundness are separated. It is even possible to divide the orbital movement into an x component and a y component. The measurement is accomplished in a single measurement. After measuring it is possible to decide what to indicate: the orbit of the mechanical object, the deviation from a nominally round surface, or the combination of both. This is possible since once the data has been obtained it is then possible to use the data once or a number of times to indicate the orbit of the mechanical object, the deviation from a nominally round surface, or the combination of both.
