Abstract: A measuring device including a moveable measuring probe and sensors coupled to the measuring probe for providing position data of the measuring probe. The measuring probe is coupled, by a cord or a wire, to a first sensor for measuring a length or change in length of the cord or wire, and to a second sensor for measuring an angle or angular displacement of the cord or the wire. The obtained position data can be graphically represented and/or used for driving an automatic machining apparatus for producing a product corresponding to the measured data.
