Abstract

A device and a method for measuring form attributes, position attributes and dimension attributes of rotatable machine elements are described. It is the object of the invention to find a possibility for measuring form attributes, position attributes or dimension attributes of a rotatable machine element which also allows axially probeable surfaces having hidden regions to be measured with high accuracy with a lower expenditure on construction. According to the invention, this object is met in that a mechanical measuring unit having a tactile measuring probe for measuring the machine element in axial direction is provided in addition to an optical measuring unit with illumination module and camera module which captures a shadow image of the machine element. The mechanical measuring unit is fixed to the optical measuring unit and has a swiveling device for swiveling the tactile measuring probe orthogonal to the rotational axis of the machine element.
