| 20110191060 | METHOD FOR MEASURING A WORK PIECE, CALIBRATION METHOD AND COORDINATE MEASURING DEVICE - A work piece is measured by at least one point of a surface of the work piece being sampled by a feeler. The feeler exerts a probing force on the surface and the feeler is deflected relative to a mounting of the feeler. On the basis of the deflection, a position of the point of the surface is determined. A directional dependence of a flexibility of the feeler is determined and/or is known. The feeler and the work piece are positioned and/or oriented relative to each other, while taking into consideration the directional dependence, such that during sampling of the point of the surface unintentional slipping of the feeler on the surface does not occur, or occurs only with low probability, or an unintentional deviation of the feeler from an intended path on the surface does not occur, or occurs only with low probability. | 08-04-2011 |
| 20110130854 | METHOD AND DEVICE FOR PRODUCING A MASTER DIE TOOL - A device and a method for the production of a master die tool for a component. The method includes the following steps: a) receiving or creating a CAD model of the component; b) deriving a surface model for the master die tool based on the CAD model of the component; c) creating the master die tool with NC machines using the surface model; d) producing an entity of the component using the master die tool; e) detecting the contours of the entity of the component by way of a computed tomography-based coordinate measuring device which supplies a 3D point cloud of surface points of the entity of the component; f) comparing the 3D points of the 3D point cloud to the CAD model, and determining whether any deviations exist beyond predetermined tolerance thresholds, and if this is the case g) modifying the surface model based on the deviations detected; h) reworking the master die tool or recreating the master die tool with the NC machines based on the modified surface model; i) repeating steps d) to h) until no more deviations exist beyond the predetermined tolerance thresholds. | 06-02-2011 |

| 20100118027 | METHOD AND MEASURING ARRANGEMENT FOR PRODUCING THREE-DIMENSIONAL IMAGES OF MEASURING OBJECTS BY MEANS OF INVASIVE RADIATION - Three-dimensional images of objects are produced from two-dimensional projection images. Invasive radiation is emitted from a radiation source, and a first set of projection images of the object is captured by a detection device. The projection images are captured at various directions of the object referenced to the radiation source and/or the detection device. A first three-dimensional image of the object is reconstructed from the first set of projection images, the first three-dimensional image is evaluated and depending on a result of the evaluation, a position and/or direction of the object in relation to the radiation source and/or in relation to the detection device is modified, and/or an operational mode of the measuring arrangement for obtaining subsequent projection images of the measuring object is adjusted. After the evaluation of the first three-dimensional image, a second set of projection images of the object is captured by the detection device. | 05-13-2010 |
| 20100100199 | CONTROL OF AN OPERATION OF A COORDINATE MEASURING DEVICE - In a method for controlling an operation of a coordinate measuring device, at least one operational parameter is determined. One value of the operational parameter is allocated to a plurality of components. A sequence for determining the operational parameter is provided for the majority of the components. The method for determining the operational parameter in the predetermined sequence for each component is now described. It starts with the component that is first in the sequence: i) if the value of the operational parameter is allocated to the component, the value is adopted as a value of the operational parameter that is available for the operation, ii) if no value of the operational parameter is allocated to the components, one available value of the operational parameter that was available until then still remains available, iii) if another component is provided in the sequence, the method is carried out with the component. | 04-22-2010 |
| 20090242744 | ARRANGEMENT FOR PRODUCING ELECTROMAGNETIC RADIATION AND METHOD FOR OPERATING SAID ARRANGEMENT - A method for operating an assembly configured to produce electromagnetic radiation, especially X-ray radiation or extreme ultraviolet radiation. Particles, especially electrons, are guided onto a target by way of an adjustable focusing device. The particles produce electromagnetic radiation in the target. At least one object, especially a calibration object, is penetrated by the electromagnetic radiation and a radiogram of the object is recorded. The radiogram or a plurality of radiograms is automatically evaluated and the focusing device is adjusted depending on the evaluation. | 10-01-2009 |
| 20090026995 | Reliable Monitoring of the Speed in Coordinate Measuring Appliances - In a method for reliably monitoring the speed of a moveable coordinate measuring device, a first value of the speed is calculated from measured values of the coordinate measurement system. The measured values contain information on positions of the coordinate measuring device. The measured values are further used to determine the coordinates of a measurement object. A second value of the speed is ascertained from measurement signals of at least one additional movement sensor. The measurement signals can also be used for controlling a drive device of the coordinate measuring device. A fault signal can be generated if the first value and/or the second value deviate from one another, from a predetermined value and/or a limit value according to a predefined criterion. | 01-29-2009 |
| 20080307662 | Method for Scanning a Surface with the Aid of a Coordinate Measuring Machine and Coordinate Measuring Machine - A method for scanning a work piece surface uses a coordinate measurement device. A probe element is brought into contact with the surface and the probe element is moved along the surface. The coordinate measurement device has a plurality of degrees of freedom, which are independent of one another, in the possible movements of the probe element with respect to the work piece. Maximum speeds which describe the maximum of a movement speed component of the probe element based on the respective degree of freedom are defined for the degrees of freedom. An estimated path on which the probe element is intended to move during scanning is predefined. The actual scanning path can differ from the estimated scanning path. A maximum scanning speed at which the estimated scanning path can be traveled with a constant speed of the probe element is determined. | 12-18-2008 |
| 20080295349 | Coordinate Measuring Machine and Method for Operating a Coordinate Measuring Machine - In a method for operating a coordinate measuring machine and to a coordinate measuring machine, a coordinate measuring device, of the coordinate measuring machine is moved in at least one direction while being driven by an electric motor. An electrical drive current which flows through the electric motor for moving the electric motor and, move the coordinate measuring device is measured. A limit value for the electrical drive current is determined on the basis of a desired speed and/or on the basis of a desired acceleration with which the electric motor or the coordinate measuring device is intended to move. If the electrical drive current reaches the limit value determined and/or if the electrical drive current exceeds the limit value determined, the coordinate measuring device is changed to a predefined state, by virtue of the computer or the microcontroller switching off one of the switches disposed in the current path. | 12-04-2008 |

A detecting device detects the radiation penetrating through the measurement object. A positioning device provided with an adjusting element is used for adjusting the position of the measurement object with respect to the rotating device. | 09-11-2008 |
