Abstract: A measuring head (1; 1a) for a tactile coordinate measuring device (22), in particular an exclusively tactile coordinate measuring device, which has several sensor devices (3, 5; 3a, 5a) for determining at least one measured value at least at one measuring point (15). Advantageously, a first sensor device (3; 3a) comprises a tactile sensor and a second sensor device (5; 5a) comprises an optical detecting means (19), wherein both sensor devices (3, 5; 3a, 5a) can be connected to the tactile coordinate measuring device (22) by a single connecting section (9; 9a). Advantageously, an existing tactile coordinate measuring device can be converted into a multi-sensor coordinate measuring device without structural modifications. Furthermore, the invention relates to a method for measuring a workpiece with a tactile coordinate measuring device and a coordinate measuring device.

Abstract: A piezo-controlled dynamic probe or feeler head for measuring installations and measuring machine, which is in an operative connection with a measurement evaluating or plotting unit and, selectively with a measuring machine control. The probe is constructed from two mutually independently operating measuring signal generating installations, which are equipped with mutually separate or independent circuits and which act in such a manner on the measuring evaluating or plotting unit and, selectively, on the measuring machine control, that upon the generation of a signal from the first measuring signal generating installation, stored data regarding the position of the probe can be recognized as being valid only at the presence of a confirmation or acknowledging signal from the second measuring signal generating installation.

Abstract: A dynamic contact or feeler head for measuring machines and for the utilization thereof in processing machines for the solution of measurement tasks. The feeler head includes a centrally inserted feeler which is deflectable in at least two coordinate directions, which is constructed so as to be tiltable about a tilting axis which is always equally distant from the feeler and always located in the same plane, and with an electromechanical, inductive or optical signal transmission.

Abstract: A mounting arrangement for the exchangeable attachment of a probe stylus or a probe styli combination on a probe for a coordinate measuring installation. The mounting arrangement is constituted from an electrically-operating clamping device with a permanent magnet and an electromagnet wherein the field from the electromagnet is superimposed on the field from the permanent magnet. A connecting member for the probe stylus or the probe styli combination is drawn through the intermediary of the clamping device against a bearing or support in the mounting member therefore on the probe which determines its position.

Abstract: Multi-coordinate measuring and testing machine which is essentially constituted from a fundamental machine unit, a scanning or sensing system which is movable in at least two coordinate directions, and a machine-controlling unit. The scanning or sensing system is constructed as a multi-sensor system and is constituted from a mechanical sensing head or probe with at least one stylus and/or a video scanner and/or a laser scanner which are controlled from a microprocessor and operate independently of each other, and which are selectively either individually actuatable by means of software connected thereto, or can be coupled to each other in a dual or triple combination.
